Depending on the radiating properties, a body will be opaque when
A. p = 0, x = 0 and a = 1
B. p = 1, x = 0 and a = 0
C. p = 0, x = 1 and a = 0
D. x = 0, a + p = 1
Answer: Option D
Solution (By Examveda Team)
Opaque body are those body where the atoms are closely packed and the light cannot pass through. Whereas a light may or may not pass through a black body depending whether it is opaque or transparent.Depending on the radiating properties, a body will be opaque when x = 0, a + p = 1.
