The coefficient of transmission and coefficient of reflection for a given body at a given temperature are 0.33 and 0.64 respectively. Then the coefficient of emission of the same body at the same temperature will be ______?

0.33

0.03

0.3

None of these

According to Kirchhoff's law:

Coefficient of emission (e) + Coefficient of reflection (r) + Coefficient of transmission (t) = 1

Given: t = 0.33, r = 0.64

e + 0.64 + 0.33 = 1

e = 1 - 0.97

= 0.03
