A physics book slides off a horizontal table top with a speed of 1.10m/s. It strikes the floor after a time of 0.400s. Find the height of the table top above the floor.

Nearly monochromatic light of wavelength 420 nm is split in two beams. The first beam traveled 105 nm to the screen more than the second beam, thus yielding a path difference of 105 nm. A) Calculate the phase difference between the two beams.
