A body is said to be opaque to the radiation if (a, r and t are coefficient of absorption, reflection and transmission respectively)

Options

  1. At =0 and a + r =1
  2. Ba = r = t
  3. Ct 0
  4. Da =0, r =1, t =1

Correct answer

A. t =0 and a + r =1

Step-by-step solution

Opaque body does not transmit any radiation directly, array ll & t =0 & a + r =1 array
