If \(\lambda\) denotes the wavelength at which the radiative emission from a black body at a temperature \(T\) is maximum, then
- A \(\lambda \propto T^{-1}\)
- B \(\lambda \propto T^4\)
- C is independent of \(T\)
- D \(\lambda \propto T\)
Answer & Solution
Correct Answer
(A) \(\lambda \propto T^{-1}\)
Step-by-step Solution
Detailed explanation
According to Wien's displacement law, \(\lambda_m \cdot T=b\)...(i) where, \(\lambda_m=\) wavelength corresponding to maximum radiation of energy from black body, \(b=\) Wien's constant and \(T=\) temperature. \(\therefore\) From Eq. (i), we get…
