Question

What is the wavelength and frequency of light? Does light have a short or long wavelength compared with radio?

Answer 1

frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. The equation that relates wavelength and frequency for electromagnetic waves is: λν=c (where λ=wavelength, ν=frequency and c=speed of light).

Radio waves have much longer wavelengths than visible light waves. Likewise red light have longer wavelength than blue light.
