Waves Review

What happens to the speed and frequency of a light wave when it passes from water to air?

• the speed increases, and the frequency remains the same

• the speed decreases, and the frequency remains the same

• the speed increases, and the frequency decreases

• the speed decreases and the frequency increasesP

The blinds are closed in a room during the daytime and all of the lights are off. Which of the following best explains why the room may still not be completely dark and you can still see all around the room?

• Light reflects off of the windows.

• Light bends around the blinds.

• Light is absorbed by the blinds.

• Light changes direction when entering through the window.

Propagating vibrations that carry energy outward in all directions from the source are used to study the interior of the Earth. These types of waves are known as —

• water waves

• seismic waves

• sound waves

• light waves

Waves superimpose on one another when two or more waves arrive at the same point and occupy the same space. Which of the following processes best escribes this behavior?

• reflection

• refraction

• interference

• diffraction

A group of students placed small objects in a ripple tank and observed the path of the water waves as they approached the obstacles. They observed the waves bending around the objects. This phenomenon can be observed in a harbor as waves bend around small boats. In order for this to occur, the wavelength of the waves must be larger than the objects they encounter. This process is best described as —

• reflection

• refraction

• diffraction

• interference

As ocean waves approach coastlines with shallower water, the waves slow down because of the force exerted on them by the seabed. Waves coming into the shore at an angle will change direction because the part of the wave nearest the shore is in shallower water than the rest of the wave. Which of the following processes best describes the behavior of the waves?

• reflection

• diffraction

• refraction

• interference

• 0.0122 m/s

• 1.77 m/s

• 2.91 m/s
