Question

radiant energy is incident on a body at the rate of 5000J/sec. If the coefficient of absorption is 0.2 and coefficient of transmission is 0.5 then amount of energy transmitted by the body is​

Answer 1

Explanation:

Q=1500J/min

=

60

1500

J/s

∈=0.9=α;ρ=0.06

So, α+ρ+τ=1

0.9+0.06+τ=1

τ=0.04

Q

absorbed

=α×Q

=0.9×

60

1500

=22.5 J/s
