If radiant energy E B emitted by the black surface strikes the non-black surface. If non-black surface has absorptivity α, it will absorb how much radiations?

If radiant energy E B emitted by the black surface strikes the non-black surface. If non-black surface has absorptivity α, it will absorb how much radiations? Correct Answer α E B

The remainder (1 – α) will be reflected back for full absorption at the black surface.
