Question

The wavelength of radiation emitted by a body depends upon (a) the nature of its surface (b) the area of its surface (c) the temperature of its surface (d) All of the above

Answer 1

Answer:

Option C

According to wien's displacement law as temperature of body increases, the maximum intensity of emissions shifts towards shorter wavelength.

λ

m

T=b(constant)

where, λ

m

is the wavelength at which maximum emission takes place at absolute temperature T.

Answer 2

Answer:

I think option c
