A) increases with temperature increasing
B) decreases with temperature increasing
C) sometimes increases sometimes decreases with increasing temperature
D) remains unaffected by temperature variation
Correct Answer: B
Solution :
: In heat radiations, greater the temperature of radiating body, greater the frequency and less the wavelength emitted. The wavelength decreases with temperature rising i.e.,\[{{\lambda }_{m}}\propto \frac{1}{T}\].
