Wave Interactions

Question 1

Sunlight is shown filtering through clouds.What wave phenomenon is responsible for the sunlight shown in this diagram?

Revolt · Accepted Answer

diffraction, because light is bent around the clouds

Question 2

What is the purpose of a rearview mirror in a car?

Revolt · Accepted Answer

The mirror allows the light to be reflected so the objects behind the car can be seen.

Question 3

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 4

What best describes the refraction of light rays?

Revolt · Accepted Answer

light bending when it passes through a lens

Question 5

Question 6

The image shows water passing through a barrier.

Revolt · Accepted Answer

diffraction

Question 7

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 8

A lens focuses light at a single point called the focal point.

Revolt · Accepted Answer

refraction

Question 9

Revolt · Accepted Answer

A triangular crest.

Question 10
