This illustration shows three different waves traveling through the same medium. How do the waves differ from one another?

The waves carry different amounts of energy.

The waves travel at different speeds.

The waves have different wavelengths.

The waves are a different distance from the source.

How are light and sound similar?

They both travel at the same speed.

They both travel through a vacuum.

How are electromagnetic waves different from other waves?

They can travel through a vacuum and through matter.

They have very short wavelengths.

They transmit energy instead of matter.

They can change direction by reflection when they strike an object.

A single beam of light is shone into a glass containing milky water. Which statement BEST describes why the beam of light bends downward?

The light is moving from air into another medium.

The milk blocks the passage of light through the water.

The force of gravity affects light more when it is in a liquid.

The farther light is from its source, the slower it moves.

The two waves above are traveling at the same speed. Which statement best describes the difference between the waves?

Wave A has a lower frequency than wave B.

Wave A has a higher frequency than wave B.

Wave A has a higher amplitude than wave B.

Wave A has a lower amplitude than wave B.

Which of the following correctly identifies the speed of sound waves in a substance?

Sound waves travel the slowest through air.

Sound waves travel the slowest through ice.

Sound waves travel the fastest through water.

Sound waves travel the same through materials

2. Samuel notices a rainbow in the sky after it has rained. He remembers learning in science class that a rainbow is a result of the interaction between light and water droplets in the sky. How could Samuel best explain why he is able to see the different colors of the rainbow?

The sunlight is refracted as different colors leave the water droplets in different directions.

The sunlight is refracted as different colors bounce off the water droplets.

The sunlight is reflected as different colors bounce off different water droplets.

The sunlight is reflected as different colors leave the water droplets at different speeds.

2. How can the behavior of light be described as it leaves the vacuum of space and enters the Earth's atmosphere?

Light waves slow down as they enter the Earth's atmosphere from space.

Light waves continue at the same speed as they enter the Earth's atmosphere from space.

Light waves speed up and then slow down as they enter the Earth's atmosphere from space.

Light waves slow down and then speed back up as they enter the Earth's atmosphere from space.

2. A projector in the back of a movie theater displays a movie on the screen at the front. Which statement best explains how you are able to see the movie on the screen at the front?

The projector sends light to the screen, which reflects most of it to the observer's eye.

The projector absorbs light from the room and sends it to the screen.

The projector sends light to the screen, which refracts the light into images.

The projector scatters light, sending it in all directions and creating pictures for the observer.

Which statement best describes the phenomenon that is occurring?

Light slows down as it moves from the air into the water causing it to refract.

Light speeds up as it moves from the air into the water causing it to refract.

Light travels in a straight line from the air into the water causing it to reflect.

Light travels in a straight line from the water into the air causing it to reflect.
