If wavelengths of visible rays, microwaves and X-rays are λᵥ, λₘ and λₓ respectively. Then out of the following which relation is correct one?

Question

Accepted Answer

(1) λₘ > λᵥ > λₓ. Idea: place the three bands on the spectrum by their typical wavelengths. Microwaves are centimetre-scale, around 10⁻² m; visible light is a few hundred nanometres, around 5×10⁻⁷ m; X-rays are around 10⁻¹⁰ m. So the microwave is the longest and the X-ray the shortest. That is λₘ > λᵥ > λₓ.
