1. Explain how the modern double-slit experiment showed different results than Young's double-slit experiment.

2. During the photoelectric effect experiment, a photon is emitted with 5.73 x10^-20 J of kinetic energy. If the work function of the photosensitive surface is 0.540 eV, which is the frequency of the incident light? Show your work. (h = 6.626 x 10^-34 Js; 1 eV = 1.60 x 10^-19 J)

3. A current-carrying wire carries a current of 0.895 A. How far away from the wire is point P if the magnetic field at that location is 5.34 x 10^-6 T?

a. 0.0335 A

b. 0.0559 A

c. 0.559 A

d. 0.335 A
