pulse. S4 [10 points]: In Young’s doubleslit experiment, suppose the separation between the two slits is
d=0.300 mm. If a beam of 500nm light strikes the slits and produces an interference pattern. How
many maxima will there be in the angular range −45.0°< < 45°? S5 [10 points]: A rocket of mass 1.40 105 kg has a relativistic momentum the magnitude of which is

You must show your work and write your answers clearly and legibly.
Partial credit may be given. All numerical answers must include the correct units. You do not need to
