suppose you conduct an experiment where you shine plane waves of light through a small slit. how would the intensity graph of this experiment differ than that of a double slit of similar width?

Expert Solution

Both in double and single slits, there is a difference in the interference pattern. Two separate wavefronts originate from two coherent sources (separate slits in this case). Secondary wavelets originating from different parts of the same wavefront constitute diffraction.
The region of minimum intensity is perfectly dark in double slit, with alternating bands of maxima and minima. The fringes (bright (maxima) or dark bands (minima)) are of equal width in double slit, whereas in single slit the pattern is that there is a central maximum fringe, which has 2 x the width of the subsidiary maxima; also, the intensity of all positions of maxima are of the same intensity in a double slit, however the intensity decreases successively along the subsidiary maxima from the central maximum fringe.

In a double-slit experiment, light with a wavelength λ passes through a double-slit and forms an interference pattern on the screen at a distance L from the slits. What statement is true for the resulting interference pattern if the frequency of the light increases? OPTIONS: The distance between maxima stays the same.T he distance between maxima increases. The distance between maxima decreases. Not enough information given.

Suppose that you shine light from a laser through two slits that are placed one in front of the other, separated by 0.6mm. The width of each slit is 0.12mm. The light will travel from the laser, through the slits, and onto a screen 1.5m away. a. Predict what you will observe on the screen, and compare it to what you would expect from single-slit diffraction. b. If ray (geometrical optics) accurately described this siutation, what would the pattern on...

Light of unknown wavelength passes through a double slit, yielding both double slit and diffraction patterns on a screen that is 1 m away from the slits. You see that the 9th double-slit maximum coincides with the 2nd single-slit diffraction minimum. You also observe that the first diffraction minimum is located 3 cm from the central axis on the screen. (a) What is the ratio of double-slit separation to single slit width, d/a? (b) If d = 72 µm, what...
