speed of light, speed at which light waves propagate through different materials. In particular, the value for the speed of light in a vacuum is now defined as exactly 299,792,458 metres per second

It has been said that large doses of radio waves can cause cancer, leukemia as well as other disorders. Some people have also claimed that overhead power cables near their homes which causes a very low-frequency field also can harm their health.

Various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications.

The range of the radio spectrum is considered to be 3 kilohertz up to 300 gigahertz. A radio wave is generated by a transmitter and then detected by a receiver.

299,775 km/s

It is shown first that, for radio waves in a vacuum, their speed of transmission is equal to the velocity of light (299,775 km/s), to within the limits of experimental error.

2)Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz.
3)We use infrared radiation in many ways, including thermal imaging cameras, remote controls, fiber optic cables, infrared astronomy, and meteorology. The fact that water vapor and other greenhouses gases absorb infrared is part of why the greenhouse effect happens.
4)Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.

1. Ultraviolet waves are incapable of travelling through vacuum, these waves can travel at the speed of sound of 300,000,000 metres per second in a vacuum
2.The frequency of a Ultraviolet wave between wavelengths of about 400 nanometres and 10 nanometres, corresponding to frequencies of 7.5 × 10 ¹⁴ Hz to 3 × 10 ¹⁶ Hz.
3.The UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning.
4.Sunburn is a sign of short-term overexposure, while premature aging and skin cancer are side effects of prolonged UV exposure. UV exposure increases the risk of potentially blinding eye diseases, if eye protection is not used. Overexposure to UV radiation can lead to serious health issues, including cancer.
