Question

Interference of light as it passes through a double slit produces a pattern of light and dark bands. Interference is evidence of what property of light?

Choices

Choice (5) Response

a.

Light has a wave nature, so that the wave patterns produced by the two slits interfere constructively and destructively to produce a pattern.

b.

Light has a wave nature, so that it cannot pass efficiently through the double slits, leaving only certain rays of light to produce a pattern on a screen.

c.

Light has a particle nature, such that the momentum of photons causes them to cancel their motions when they collide.

d.

Light is attenuated, or absorbed, by the region around the double slits, leaving only certain beams of light and producing a pattern of light and dark.

e.

Question does not provide sufficient data or is vague
