72. A beam of red laser light (wavelength = 633 nm) hits a black wall and is fully absorbed. If this exerts a total force of F = 5.5 nN, how many photons per second are hitting the wall?
Use that de Broglie's relation of momentum p = h/lambda. Force is just change in momentum/time - so the number of photons per second times the momentum of each would give the force.. (1 nN = 10-9 N)
