In the spectrum of a back body at two temperature

{T}

and

2 {T}

, let

{A}_1

and

{A}_2

be area under the two curves respectively. The value of

\frac{A_1}{A_2}

will be

View answer and explanation

Correct option: A

1: 16

Option A (

1: 16

) is correct because the area under the black body spectrum curve is proportional to the fourth power of the temperature, according to Stefan-Boltzmann law.
