Question :Identify the electromagnetic wave whose wavelengths range is from about
(a) 10-12 m to about 10-8 m
(b) 10- m to about 10-1 m.
Write one use of each.
The correct answer is -(a) The electromagnetic wave whose wavelengths range is from about 10-12 m to about 10-8 m is a gamma ray. One use of gamma rays is in cancer treatment, where high-energy gamma rays are used to kill cancer cells.
(b) The electromagnetic wave whose wavelengths range is from about 10-7 m to about 10-1 m is a microwave. One use of microwaves is in communication, where they are used in microwave ovens, cell phone towers, and satellite communication.
