Transmission Of Heat Question 313
Question: The maximum wavelength of radiations emitted at 900 K is $ 4\mu m $ . What will be the maximum wavelength of radiations emitted at 1200 K
Options:
A) $ 3\mu m $
B) $ 0.3\mu m $
C) $ 1\mu m $
D) $ 1,,m $
Show Answer
Answer:
Correct Answer: A
Solution:
$ \frac{{\lambda _{2}}}{{\lambda _{1}}}=\frac{T _{1}}{T _{2}}\Rightarrow {\lambda _{2}}=\frac{T _{1}}{T _{2}}\times {\lambda _{1}}=\frac{900}{1200}\times 4=3\mu m $
