Q1. Assuming that the maximum amplitude of the field at point O for the wave from midway between the slits is E(r), now find out the magnitude of the combined field E at O due to the two slits. You could ignore variations in the maximum amplitude and consider only variations in phase of the waves emerging from the slits.
Express the answer in terms of E(r), phi, and delta phi.
Q2. An electron is projected with an initial speed 1.00×106 into the uniform field between the parallel plates. Suppose that field between the plates is uniform and fixed vertically downward, and that field outside the plates is zero. The electron enters the field at the point midway between the plates.
If the electron just misses the upper plate as it emerges from the field, find out the speed of the electron as it emerges from the field?
