Question

For any material, if R, T and A represent the reflection coefficient, transparent coefficient and absorption coefficient respectively, then for a blackbody which one of the following is true (A) R=1, T=0, A=0 (B) R=0, T=1, A=1 (C) R=0, T=0, A=1 (D) R=0, T=1, A=0

∵ Relation between R, T and A is A+T+R=1 ...(i) ∵ For ideal blackbody, A=1 ∴ According Equation (i), R=0, T=0 and A=1

Q. For any material, if $R, T$ and $A$ represent the reflection coefficient, transparent coefficient and absorption coefficient respectively, then for a blackbody which one of the following is true

$R = 1, T = 0, A = 0$

$R = 0, T = 1, A = 1$

$R = 0, T = 0, A = 1$

$R = 0, T = 1, A = 0$

$∵$ Relation between $R, T$ and $A$ is
$A + T + R = 1$ ...(i)
$∵$ For ideal blackbody,
$A = 1$
$∴$ According Equation (i),
$R = 0, T = 0$ and $A = 1$

Q. For any material, if R,T and A represent the reflection coefficient, transparent coefficient and absorption coefficient respectively, then for a blackbody which one of the following is true

R=1,T=0,A=0

R=0,T=1,A=1

R=0,T=0,A=1

R=0,T=1,A=0
