Coefficient of transmission is 0.22 and ...

Coefficient of transmission is 0.22 and coefficient of reflection is 0.74 for a given body. For a given body, at given temperature, the coefficient of emission is

A

0.4

B

0.04

C

0.96

D

0.22

Text Solution

Verified by Experts

The correct Answer is:
B
`a+r+t=1`
`a=1-(r+t)`
`=1-(r+t)`
`=1-(0.22+0.74)`
`=1-0.96`
`a=0.04`.
