Question

An athermanous metal plate has the coefficient of absorption 0.65 its coefficient of reflection is

Answer 1

Answer:

0.35

Explanation:

The coefficient of absorption+coefficient of reflection=1

then, 0.65+coefficient of reflection=1

hence, coefficient of reflection=0.35

Answer 2

Given:

• Coefficient of absorption = 0.65

To Find:

• Coefficient of reflection.

Solution:

We have a formula that states,

coefficient of absorption+coefficient of reflection = 1 → {equation 1}

on substituting the values in equation 1 we get,

⇒ 0.65 + coefficient of reflection = 1

⇒ coefficient of reflection = 1-0.65 {subtracting the terms}

⇒ coefficient of reflection = 0.35

∴ The coefficient of reflection = 0.35
