A small surface of area A = 1 cm 2 is subjected to incident radiation of constant

Question:

A small surface of area A = 1 cm² is subjected to incident radiation of constant intensity I_i = 2.2 × 10⁴ W/m² · sr over the entire hemisphere. Determine the rate at which radiation energy is incident on the surface through

(a) 0 ≤ θ ≤ 45°

(b) 45 ≤ θ ≤ 90°, where θ is the angle a radiation beam makes with the normal of the surface.
