Wave Interactions

Question 1

Study the image below.What interaction causes the water to spread as they pass through the rock opening?

Revolt · Accepted Answer

diffraction

Question 2

If a soundproof door is almost shut but still leaves a small opening, what wave phenomenon is responsible for someone being able to hear sound from the room while standing by the wall to the side of the opening?

Revolt · Accepted Answer

diffraction

Question 3

Two pulses are moving along a string. One pulse is moving to the right and the second is moving to the left. Both pulses reach point P at the same instant.

Revolt · Accepted Answer

An illustration with a rectangular crest moving toward the right past P and a triangular trough going toward the left past P.

Question 4

Which is the best example of the wave phenomenon called transmission?

Revolt · Accepted Answer

A street is seen through a window.

Question 5

The two waves in the diagram are occupying the same place at the same time.At what time will the interfering waves have an amplitude of zero?

Revolt · Accepted Answer

4.0

Question 6

The appearance of color is a result of the absorption and reflection of certain wavelengths of light. A shirt appears a certain color because it reflects that color of light. On the other hand, a shirt appears black when it absorbs all wavelengths of light and white when it reflects all wavelengths of light.

Revolt · Accepted Answer

The temperature of the shirt will increase because all wavelengths of light are absorbed by the shirt.

Question 7

In 1940, the Tacoma Narrows Bridge across the Puget Sound collapsed. The bridge was a suspension bridge. The wind blowing through the narrows matched the natural frequency of the bridge. This resulted in a large movement of roadway, which eventually caused the bridge to fail.

Revolt · Accepted Answer

interference, because constructive interference occurred when the wind frequency matched the natural frequency of the bridge

Question 8

Two wave pulses move toward each other along a rope.

Revolt · Accepted Answer

A triangular crest.

Question 9

Color is a result of the absorption and reflection of light. A shirt appears a color because it reflects that color of light. A shirt appears black when it absorbs all wavelengths of light.

Revolt · Accepted Answer

All the light is reflected, so the shirt appears white.

Question 10

The image shows water passing through a barrier.

Revolt · Accepted Answer

diffraction
