Solution

The correct option is D 0.04
Coefficient of absorption $+$ Coefficient of transmission $+$ Coefficient of reflection $= 1$
$\Rightarrow 0.73 + 0.23 +$ coefficient of reflection $= 1$
$\Rightarrow$ Coefficient of reflection $= 0.04$

The correct option is D 0.04Coefficient of absorption +Coefficient of transmission + Coefficient of reflection =1⇒0.73+0.23+ coefficient of reflection =1⇒Coefficient of reflection =0.04

The correct option is D 0.04
Coefficient of absorption $+$ Coefficient of transmission $+$ Coefficient of reflection $= 1$
$\Rightarrow 0.73 + 0.23 +$ coefficient of reflection $= 1$
$\Rightarrow$ Coefficient of reflection $= 0.04$
