Q1: Wavelength of radiation emitted by a body depends on the __________ of its surface.A temperature
B area
C nature
D all 'a', 'b' & 'c'
ANS:A - temperature The wavelength of radiation emitted by a body depends on the temperature of its surface. This is described by Wien's displacement law, which states that the wavelength of maximum emission (peak wavelength) of blackbody radiation is inversely proportional to the temperature of the emitting body. In other words, as the temperature of the body increases, the peak wavelength of radiation emitted decreases. Therefore, the correct choice is: temperature |
