The surface temperature of the stars is determined using

Options

  1. APlanck's law
  2. BWien's displacement law
  3. CRayleigh-Jeans law
  4. DKirchhoff's law

Correct answer

B. Wien's displacement law

Step-by-step solution

The surface temperature of the stars is determined using Wien's displacement law. According to this law, _ m ~T = b where b is Wien's constant whose value is 2.898 10⁻³ mK
