1a. For diffraction from a single slit, sketch the expected form of the diffraction pattern.

1b. In terms of the width of the slit, a, where would you expect to find the first minimum? As part of your answer consider points of the edge of the slit and in the middle of the slit, and the path difference between light waves originating at each point to a point on the screen that would result in destructive interference. Explain your answer.

Light with a wavelength of 550 nm is incident on a single slit, creating a diffraction pattern on a distant screen 2.5 m away. At a point on the diffraction pattern that is 1.443 m from the central maximum, the path length difference between the ray from the top of the slit and the bottom of the slit results in a phase difference of 6π radians. What is the width of the slit? (a) 1.1 µm (b) 2.2 µm (c)...

1. A single slit produces a diffraction pattern on a distant screen. Show that the separation distance between the two minima on either side of the central maximum is twice as large as the separation distance between all the other neighbouring minima. Compare your result to the corresponding case for a double-slit pattern with very narrow slits.

1) A two slit interference/diffraction pattern is set up (thus for this problem we will take into account the effects of both diffraction and interference). You are given that the screen is 1.8 m away from the slits with width .01 mm and spacing .05 mm and light of wavelength 640 nm is used. What is the smallest order interference maximum that is \"missing\" from the interference/diffraction pattern on the screen? n=
