Temperature of the star is determined by

Options

  1. Adistance
  2. Bcolour
  3. Csize
  4. Dnone of these.

Correct answer

B. colour

Step-by-step solution

We know from Wien's displacement law that _m T=b , where _m= wavelength of light emitted with maximum intensity. T= Temperature of the star From the colour (wavelength) of the emitted light, we can determine the temperature of the star.
