Depending on the radiating properties, a body will be black when
(Where a = absorptivity, p = reflectivity, x = transmissivity.)
A. p = 0, x = 0 and a = 1
B. p = 1, T = 0 and a = 0
C. p = 0, x = 1 and a = 0
D. x = 0, a + p = 0
Answer: Option A
Solution (By Examveda Team)
Depending on the radiating properties, a body will be black when, p = 0, x = 0 and a = 1(Where a = absorptivity, p = reflectivity, x = transmissivity)
