Question

A black body is at 727∘C. It emits energy at a rate which is proportional to:

Answer 1

energy proportional to temperature ^4 ( in Kelvin )

Answer 2

E=hc/kanda

h and C is constant

so energy inversely proportional to LAMDA

and

frequency =C/LAMDA

so frequency inversely proportional to LAMDA

there for energy directly proportional to frequency
