Suppose a power source (having power P) is at distance r from the metal plate and photons are assumed to strike the plate normally.

Intensity of light reaching the plate is: I = P/4.PI.r^2

If plate area is A, we say power received is: P(R) = I.A = n

Now, my question is how suddenly we merged wave theory and quantum theory in equation (1).
