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.
Reading this solution needs no sign-in. You only sign in to practise against the clock and keep your progress.
