Question

(b) Radio waves are part of the electromagnetic spectrum. They travel through air at
3.0 x 10 m/s
The frequency of a radio wave is 2 x 106 Hz.
Calculate its wavelength,

Answer 1

Answer:

Radio > 1 x 10-1 < 3 x 109

Explanation:

the wavelengths of radio waves range from thousands of metres to 30 cm. These correspond to frequencies as low as 3 Hz and as high as 1 gigahertz (109 Hz).

Most of the radio part of the EM spectrum falls in the range from about 1 cm to 1 km, which is 30 gigahertz (GHz) to 300 kilohertz (kHz) in frequencies. The radio is a very broad part of the EM spectrum. Infrared and optical astronomers generally use wavelength.
