The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.
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 both UHF 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.
The Police were an English rock band formed in London in 1977. For most of their history the line-up consisted of primary songwriter Sting, Andy Summers (guitar) and Stewart Copeland. The Police became globally popular in the late 1970s and early 1980s. Emerging in the British new wave scene, they played a style of rock influenced by punk, reggae, and jazz.
Synth-pop is a subgenre of new wave music that first became prominent in the late 1970s and features the synthesizer as the dominant musical instrument. It was prefigured in the 1960s and early 1970s by the use of synthesizers in progressive rock, electronic, art rock, disco, and particularly the Krautrock of bands like Kraftwerk. It arose as a distinct genre in Japan and the United Kingdom in the post-punk era as part of the new wave movement of the late 1970s to the mid-1980s.
Power pop is a form of pop rock based on the early music of bands such as the Who, the Beatles, the Beach Boys, and the Byrds. It originated in the 1960s and developed mainly among American musicians who came of age during the British Invasion as they began to rebel against the emerging pretensions of rock music. The genre typically incorporates melodic hooks, vocal harmonies, an energetic performance, and "happy" sounding music underpinned by a sense of yearning, longing, or despair.
Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band and the far infrared band, the lower part of which is the terahertz band. Radio waves in this band have wavelengths from ten to one millimetre, so it is also called the millimetre band and radiation in this band is called millimetre waves, sometimes abbreviated MMW or mmWave. Millimetre-length electromagnetic waves were first investigated by Indian physicist Jagadish Chandra Bose during 1894–1896, when he reached up to 60 GHz in his experiments.
Girl power is a slogan that encourages and celebrates women's empowerment, independence, confidence and strength. The slogan's invention is credited to the US punk band Bikini Kill, who published a zine called Bikini Kill #2: Girl Power in 1991. It was then popularized in the mainstream by the British girl group Spice Girls in the mid-1990s.
A gamma wave or gamma Rhythm is a pattern of neural oscillation in humans with a frequency between 25 and 140 Hz, the 40-Hz point being of particular interest. Gamma rhythms are correlated with large scale brain network activity and cognitive phenomena such as working memory, attention, and perceptual grouping, and can be increased in amplitude via meditation or neurostimulation. Altered gamma activity has been observed in many mood and cognitive disorders such as Alzheimer's disease, epilepsy, and schizophrenia.

Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 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 very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications.
Waves most often refers to:
In telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones. 5G networks are predicted to have more than 1.7 billion subscribers worldwide by 2025, according to the GSM Association. Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. The main advantage of the new networks is that they will have greater bandwidth, giving higher download speeds, eventually up to 10 gigabits per second (Gbit/s). In addition to 5G being faster than existing networks, 5G can connect more different devices, and even if people are in crowded areas, the servers will be more unified, improving the quality of Internet services. Due to the increased bandwidth, it is expected the networks will increasingly be used as general internet service providers (ISPs) for laptops and desktop computers, competing with existing ISPs such as cable internet, and also will make possible new applications in internet-of-things (IoT) and machine-to-machine areas. 4G cellphones are not able to use the new networks, which require 5G-enabled wireless devices.
CNBLUE is a South Korean pop rock band formed in 2009. The band consists of Jung Yong-hwa, Kang Min-hyuk (drums), and Lee Jung-shin (bass). First bassist Kwon Kwang-jin left the band after they released their debut Japanese extended play Now or Never in 2009, and was replaced by Lee Jung-shin. Lee Jong-hyun left the band on August 28, 2019.
