Two lasers are sent through the same double-slit device. A blue laser has a wavelength of

430nm, and a red laser has a wavelength of 645nm. The spacing of the slits is 2mm, and the

distance to the screen is 1.0m.

A) Sketch what the blue laser will look like on the screen; give a distance scale.

B) On your diagram, find a point at which both the red light and blue light will be at a bright

fringe. Show supporting calculations.

C) On your diagram, find a point at which red light is maximum, but the blue light is

*minimum*. (All red light, no blue light.) Show supporting calculations.

D) Qualitatively, what happens to the light on the screen if one of the slits is blocked?

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.

A double slit experiment is conducted with a red laser with wavelength l = 700 nm. The distance between the slits and the viewing screen is L = 2.00 m. Consider two experiments that have different slit spacings: Experiment A with dA = 2.00 μm and Experiment B with dB = 40.0 μm. For each experiment, calculate the following (be sure to keep at least three significant figures in all your intermediate calculations): a) Using Δr = d sinθ ,...

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...
