A body at \(3000 \mathrm{~K}\) emits maximum energy at a wavelength of \(9660 Å\). If the sun emits maximum energy at a wavelength of \(4950 Å\), what would be the temperature of the sun?
- A \(5855 \mathrm{~K}\)
- B \(7000 \mathrm{~K}\)
- C \(4250 \mathrm{~K}\)
- D \(8000 \mathrm{~K}\)
Answer & Solution
Correct Answer
(A) \(5855 \mathrm{~K}\)
Step-by-step Solution
Detailed explanation
Temperature of body, \(T_1=3000 \mathrm{~K}\) Body emits maximum energy at wavelength, \(\lambda_1=9660 Å\) Wavelength of radiation emitted by sun, \(\lambda_2=4950 Å\) Sun's temperature, \(T_2=\) ? According to Wien's displacement law,…
