Q1. A thin film with index of refraction n = 1.29 is placed in one arm of a Michelson interferometer, perpendicular to the optical path. If this causes a shift of 8.0 bright fringes of the pattern produced by light of wavelength 693nm, what is the film thickness?
Q2. A block of wood is placed on a frictionless horizontal surface and a 7.00 g bullet is fired from a gun into the 1.00kg black of wood and remains embedded. The bullet has an initial speed of 500m/s.
a. find the speed of the block and bullet after collision.
b. find the impulse delivered to the block by bullet
c. if the collision time is 2x10-4s, what is an average force exerted by the black on bullet
