Question

A black body emits radiations of maximum intensity at a wavelength of 5000 $\text{Å}$, when the temperature of the body is ${1227}^{o}C$. If the temperature of the body is increased by ${1000}^{o}C$, the maximum intensity of emitted radiation would be observed at

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

${\lambda }_{m1}=\frac{T_1}{T_2}\times {\lambda }_{m1}=\frac{1500}{2500}\times 5000=3000\text{Å}$
