Question

For a perfectly reflecting body:
( Given a→ absorptive power, r→ reflective power, t→ transmissive power.)

• A. $t=0,a=0$
• B. $r=0,t=0$
• C. $r=0,a=0$
• D. $r=a=t$

Answer 1

The correct option is A $t=0,a=0$

We know that:
$r+a+t=1$
For a perfectly reflecting body:
$r=1$ [Since, body reflects all the radiations falling on the body]
$\Rightarrow a=t=0$
Option, $\left(a\right)$ is correct.
