If the wavelengths of γ-rays, X-rays and microwaves are λ_γ, λₓ and λₘ then

Asked in GUJCET 2016 · Order of the bands

Answer: (2) λ_γ < λₓ < λₘ

Step-by-step solution

Idea: along the spectrum the photon energy rises and the wavelength falls, and these three sit far apart on it.

Typical values: microwaves a few centimetres, X-rays about 10⁻¹⁰ m, γ-rays about 10⁻¹² m and shorter.

So the shortest is λ_γ, then λₓ, and the longest is λₘ.

That is λ_γ < λₓ < λₘ.
