question:

context:

A) What is the intensity pattern on the screen, i.e., function 7(x), if both slits are open? provide your result in form or real (exponential and a trigonometric) functions B) Make a sketch of the probability density on the screen, 1(x) (without using any potting tool, just draw an image by hand), and assume that both a and 8 are small numbers. Explain how will the resulting function look if if a and B increase. (IV) We consider a double-slit experiment for electromagnetic waves, in which we observe the intensity of light on a screen, given by the expression: 1(x) = (x) where E is the amplitude of the electromagnetic wave and e-coordinate represents the position on the screen. If slit 1 is closed, the amplitude of the electromagnetic wave on the screen is: Ex(x) = Ve$el-07 ) If slit 2 is closed, the amplitude of the electromagnetic wave on the screen is: Ez(t) = -el-03-B2) e
