46. a) Explain why a pattern of bright and dark fringes is visible on a screen when a light is

shone through a double slit.

b) Upon using Thomas Young’s double-slit experiment to obtain measurements, the

following data were obtained. Use these data to determine the wavelength of light

being used to create the interference pattern. Do this in three different ways.

• The angle to the eighth maximum is 1.12°.

• The distance from the slits to the screen is 302 cm.

• The distance from the first minimum to the fifth minimum is 2.95 cm.
