Transmission Of Heat Question 273
Question: Solar radiation emitted by sun resembles that emitted by a black body at a temperature of 6000 K. Maximum intensity is emitted at a wavelength of about 4800Å. If the sun were to cool down from 6000 K to 3000 K then the peak intensity would occur at a wavelength

B) 9600Å
C) 7200Å
D) 6400Å
Show Answer
Answer:
Correct Answer: B
Solution:
$ {\lambda _{m _{2}}}=\frac{{\lambda _{m _{1}}}T _{1}}{T _{2}}=\frac{4800\times 6000}{3000} $ =$ 9600{\AA} $
