In modern physics, the double-slit experiment demonstrates that light and matter can satisfy the seemingly-incongruous classical definitions for both waves and particles, which is considered evidence for the fundamentally probabilistic nature of quantum mechanics. This type of experiment was first performed by Thomas Young in 1801, as a demonstration of the wave behavior of visible light. At that time it was thought that light consisted of either waves or particles. With the beginning of modern physics, about a hundred years later, it was realized that light could in fact show behavior characteristic of both waves and particles. In 1927, Davisson and Germer demonstrated that electrons show the same behavior, which was later extended to atoms and molecules. Thomas Young's experiment with light was part of classical physics long before the development of quantum mechanics and the concept of wave–particle duality. He believed it demonstrated that Christiaan Huygens' wave theory of light was correct, and his experiment is sometimes referred to as Young's experiment or Young's slits.
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity and to distinguish it from spatial frequency. Frequency is measured in hertz which is equal to one event per second. Ordinary frequency is related to angular frequency by a scaling factor of 2π. The period is the interval of time between events, so the period is the reciprocal of the frequency, f=1/T.
Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes UHF, SHF and EHF bands. A more common definition in radio-frequency engineering is the range between 1 and 100 GHz. In all cases, microwaves include the entire SHF band at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations.
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.
In physics and mathematics, wavelength or spatial period of a wave or periodic function is the distance over which the wave's shape repeats. In other words, it is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings. Wavelength is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The inverse of the wavelength is called the spatial frequency. Wavelength is commonly designated by the Greek letter lambda (λ). The term "wavelength" is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids.
Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz (GHz) and below. At 300 GHz, the corresponding wavelength is 1mm, which is shorter than the diameter of a grain of rice. At 30 Hz the corresponding wavelength is ~10,000 kilometers longer than the radius of the Earth. Wavelength of a radio wave is inversely proportional to its frequency, because its velocity is constant. Like all electromagnetic waves, radio waves in a vacuum travel at the speed of light, and in the Earth's atmosphere at a slightly slower speed. Radio waves are generated by charged particles undergoing acceleration, such as time-varying electric currents. Naturally occurring radio waves are emitted by lightning and astronomical objects, and are part of the blackbody radiation emitted by all warm objects.
In quantum physics, a wave function is a mathematical description of the quantum state of an isolated quantum system. The wave function is a complex-valued probability amplitude, and the probabilities for the possible results of measurements made on the system can be derived from it. The most common symbols for a wave function are the Greek letters ψ and Ψ.
A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.
Seventh grade is the seventh year of formal or compulsory education. The seventh grade is typically the second or third year of middle school. Children in seventh grade are around 12–13 years old. Different terms and numbers are used in other parts of the world.
The WaveBird Wireless Controller is a radio frequency-based wireless controller manufactured by Nintendo for use with the GameCube home video game console. Its name is a reference to Dolphin, the GameCube's codename during development. The WaveBird was available for purchase separately as well as in bundles with either Metroid Prime or Mario Party 4, which were exclusive to Kmart in the US.
Rudolf Kompfner was an Austrian-born inventor, physicist and architect, best known as the inventor of the traveling-wave tube (TWT).
In music, the septimal minor third, also called the subminor third or septimal subminor third, is the musical interval exactly or approximately equal to a 7/6 ratio of frequencies. In terms of cents, it is 267 cents, a quartertone of size 36/35 flatter than a just minor third of 6/5. In 24-tone equal temperament five quarter tones approximate the septimal minor third at 250 cents. A septimal minor third is almost exactly two-ninths of an octave, and thus all divisions of the octave into multiples of nine have an almost perfect match to this interval. The septimal major sixth, 12/7, is the inverse of this interval.
Gravitational waves are waves of the intensity of gravity that are generated by the accelerated masses of an orbital binary system, and propagate as waves outward from their source at the speed of light. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as waves similar to electromagnetic waves but the gravitational equivalent.
The Game Wave Family Entertainment System, commonly abbreviated as Game Wave, is a hybrid DVD player and home video game console manufactured by ZAPiT Games. It is part of the seventh generation of video game consoles.

"Love Is the Seventh Wave" is a hit single from Sting's 1985 solo debut album The Dream of the Blue Turtles. It was released as the album's second single in the UK, and the third single in the US.
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 3,000 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications.
West Seventh is a neighborhood in Saint Paul, Minnesota, United States. This area is colloquially known as the West End, and is not to be confused with the West Side, a different neighborhood. The West End lies at the base of Summit Hill and along the western bluffs of the Mississippi River, spanning the entire length of West Seventh Street, or Old Fort Road; it is also known as the Fort Road area. Fort Road was a historic Native American and fur trader path along the Mississippi River from downtown Saint Paul to Fort Snelling.
The Search for Everything: Wave Two is an extended play (EP) by American singer-songwriter John Mayer. Released on February 24, 2017 by Columbia and Sony Music, the EP contains four tracks from Mayer's seventh studio album, The Search for Everything, and is a follow-up to its predecessor EP, The Search for Everything: Wave One. It includes the lead single "Still Feel Like Your Man".
In the German Wehrmacht before and during World War II, infantry divisions were raised as part of a designated Aufstellungswelle or Welle (wave), sometimes translated as "draft". The Aufstellungswelle system was adopted by the Wehrmacht in late 1938. Peacetime units were the first wave, and 34 other waves followed until the 35th wave in April 1945. Several types of divisions were organized by Aufstellungswelle, including infantry, security, shadow and Volksgrenadier divisions.
