Consider an electromagnetic harmonic plane wave, where the peak electric field amplitude is 1 N/C.
a) What is the irradiance of this plane wave?
b) Consider such a wave with a frequency in the centre of the visible band of the electromagnetic spectrum. What is the number of photons passing through an area of 1 m² in 1 second? (Assume the area the light is passing through is perpendicular to the wave’s propagation direction).
c) Now consider two additional waves - one in centre of the microwave band, and the second in the centre of the X-ray band. Repeat part b) for each of these two waves.
