In an experiment, monochromatic light of λ= 400. nm is incident on a a single slit by a width of 1600.nm. Bright and dark fringes are view on a screen and teh angular positions of the maxima and the minima are measured.
Compute the first two angles at which the intensity of the light is at a minimum.
Consider the infinite square well of width a. V(x) is infinite out side well and zero inside. Discuss the importance of the quantum effects for both of these systems. Use the uncertainty principle to estimate the velocities of the electron and the me..
