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. (Hint: use the formula for intensity of single slit diffraction)

2.Two ordinary lightbulbs S1 and S2 are 1m apart, each emitting light waves with intensity I, mainly at a wavelength of 550 nm. What is the pattern of intensity on a screen 100m away?

In a double-slit experiment, if the slit separation is increased, how will the interference pattern on the screen change? If instead, you increase the distance between the slit and the screen, how will the interference pattern change? (i.e. the maxima and minima stay in the same position, get further apart, get closer together, etc.)

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.
