Which best describes electromagnetic waves moving from gamma rays to radio waves along the electromagnetic spectrum? wavelength and frequency decrease. wavelength and frequency increase. wavelength increases, and frequency decreases. wavelength decreases, and frequency increases.

wavelength increases and frequency decreases.

Electromagnetic spectrum is formed of radiations varying in frequency and wavelength like gamma rays, radio waves, UV rays, visible, microwaves, etc.

We know that wavelength is inversely proportional to frequency.

Gamma rays have frequency greater than and radio waves frequency 300 GHz=.

hence, moving from gamma rays to radio waves, frequency decreases. And, since the wavelength is inversely proportional to frequency, the wavelength increases.
