Figure Q17.7 shows the viewing screen in a double-slit experiment with monochromatic light. Fringe C is the central maximum.

A B C D E FIGURE Q17.7

a. What will happen to the fringe spacing if the wave-length of the light is decreased?

b. What will happen to the fringe spacing if the spacing between the slits is decreased? 

c. What will happen to the fringe spacing if the distance to the screen is decreased? 

d. Suppose the wavelength of the light is 500 nm. How much farther is it from the dot on the screen in the center of fringe E to the left slit than it is from the dot to the right slit?
