The coefficient of reflection of an opaque body is 0.16. Its coefficient of emission is

A

0.94

B

0.84

C

0.74

D

0.64

Text Solution

Verified by Experts

The correct Answer is:
B

For a body a + r + t = 1
For an opaque body, coefficient of transmission (t) = 0
`thereforea+0.16+0=1" "thereforea=1-0.16=0.84`
`thereforea=e=0.84`
