If the temperature of back body is doubled, the frequency at which the spectral intensity becomes maximum, will be

Options

  1. Aunchanged
  2. Bfour times
  3. Cdoubled
  4. Dhalved

Correct answer

C. doubled

Step-by-step solution

According to the Wein's displacement law: _m 1 T And the relation between wavelength and frequency is: aligned & 1 f & f T aligned Thus, if T is doubled, the frequency at which the spectral intensity becomes maximum f is also doubled.
