Question : The wavelength at which the peak of intensity of black body radiation occurs
Option 1: increases with an increase in temperature
Option 2: decreases with an increase in temperature
Option 3: is the same at all temperatures
Option 4: does not follow any pattern as temperature changes
Correct Answer: decreases with an increase in temperature
Solution : The correct option is to decrease with an increase in temperature .
This observation is described by Wien's law, which states that the wavelength (λ) at which the intensity of black body radiation is at its maximum is inversely proportional to the absolute temperature (T) of the object. This indicates that when the black body's temperature rises, the wavelength of the peak intensity decreases.
