4. A blue photon (A = 400 nm) reflects off a fixed surface and travels backwards. A A) Calculate the energy of this photon, in eV. B) Determine the linear momentum of this photon, in kg m/s. Then, calculate this in eV/c. C) Suppose this photon reflects in 1x10-10 s. Calculate the force this photon exerts on the surface. D) How many blue photons would be required to exert 1 N of force on the surface, using the information in part (C)? Then, calculate the energy required to accomplish this.
