Question

A massless spring attached to a wall lies on a frictionless table. It has an object of mass attached to one end. Initially the object is at rest. Another object, also of mass is sliding along on the tabletop with a speed of . At time , the moving object collides with object on the spring. The two stick together and oscillate back and forth. If the spring constant is , find an expression which describes the motion of the two objects that are stuck together.

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 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.

b.

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

c.

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.

d.

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

e.

None of the above
