Question

if reflectance and transmittance of a body are 0.4 and 0.3, then it's absorptance will be​

Answer 1

0.3

Explanation:

Since ,

a + r + t = 1

a = 1 - r - t

Answer 2

Let reflectance be 0.4

Let transmittance be 0.3

absorptance=?

Explanation:

Absorptance = T + R + A = 1

A= 1 - T - R

   =1 - 0.3 - 0.4

   = 0.3
