Answer #1

Solution

Answer: 7.39511*10^{22} photons per second

The calculations are based in the given idea that the photons are completely absorbed by the bead such that they transfer their complete incident momentum to the beads. For equilibrium the downward force must be balanced by upward force exerted by colliding photons. This process is completely inelastic.

    Suppose you designed a spacecraft to work by photon pressure. The sail was a completely absorbing fabric of area 1.0 km2 and you directed a laser beam of wavelength 650 nm onto it at a rate of 1 mol of photons per second from a base on the moon. What is (a) the force, (b) the pressure exerted by the radiation on the sail? (c) The spacecraft has a mass of 1.0 kg. Given that, after a period of acceleration...
