The E.M. wave with shortest wavelength among the following is

The E.M. wave with shortest wavelength among the following is
  1. Ultraviolet rays
  2. X-rays
  3. Gamma-rays
  4. Microwaves

Solution

If we look at the spectrum of electromagnetic waves then the order of a wavelength is, λgamma<λX-ray<λUV rays<λVisible<λInfrared<λMicrowave<λRadio, so from the above spectrum the wavelength of gamma rays is minimum and then the wavelength of a radio wave is maximum, so the shortest wavelength is for gamma-rays.
