Choose the correct option relating wave lengths of different parts of electromagnetic wave spectrum: (a) λ radio waves > λ micro waves > λ visible > λ x-rays (b) λ visible > λ x-rays > λ radio waves > λ micro waves (c) λ visible < λ micro waves < λ radio waves < λ x-rays (d) λ x-rays < λ micro waves < λ radio waves < λ visible

Answer: (a). Order of wavelength (longest to shortest): radio > microwave > infrared > visible > UV > X-rays > γ -rays. So λradio > λmicro > λvisible > λX. So the answer is (a).

Electromagnetic Spectrum & Atmosphere

Choose the correct option relating wave lengths of different parts of electromagnetic wave spectrum:

Show answer and solution

Answer: (a)

Order of wavelength (longest to shortest): radio > microwave > infrared > visible > UV > X-rays > $\gamma$ -rays.
So $\lambda_{radio} > \lambda_{micro} > \lambda_{visible} > \lambda_{X}$ .
So the answer is (a).
