A horizontal beam of laser light of wavelength is 585 nm passes through a narrow slit that has width 0.0602mm. The intensity of the light is measured on a vertical screen that is 2.00 m from the slit. (a) What is the minimum uncertainty in the vertical component of the momentum of each proton in the bean after the photon has passed through thr slit? What is the width of the central maximum and the intensity in terms of I0 at the first minimum? (b) If these photons scatters off an electron at rest at an angle of 15 degrees, what is the photon's final energy? (c) If these photons strike a metal surface with work function 2.2eV, what would be the maximum kinetic energy of the emitted electrons?
The average energy of a photon in a pulsed laser beam is2.39 eV, with a minimum uncertainty of 0.0155 eV. Each pulse has anaverage of 5.00 * 10^12 photons. Find (a) the time duration of eachpulse, (b) the wavelength of the light, and (c) the energy per pulse in J.
