Waves Review

Which statement best explains the behavior of light occurring in the image?

• Green light is being refracted faster while other light is being absorbed

• Green light is being absorbed while other colors of light are being reflected

• Green light is being refracted while other colors of light are being reflected

• Green light is being reflected while all other colors of light are being absorbed

The duck in the image appears to be broken. Which best describes the phenomenon that is occurring?

• the sunlight is absorbed by the air, causing it to reach the duck's body underwater slower than the rest of the duck

• the sunlight reflects off the duck's back and then enters the water making it look different than the rest of the duck

• the sunlight is refracted as it enters the water, making the duck's body underwater appear different than the rest of the duck

• the sunlight is scattered as it enters the water, making the duck's body underwater appear different than the rest of the duck

Sam observes a rainbow in the sky right after it has rained. He remembers from science class that a rainbow is created by sunlight striking droplets of water in the air. How could Sam explain what happens to the sunlight when it strikes the water that causes the appearance of the rainbow?

• the sunlight is absorbed by the droplet of water

• the sunlight is reflected by the droplet of water

• the sunlight is refracted and bounces off the droplet of water

• the sunlight is refracted and changes direction as it leaves the water

What happens to light waves as they travel through the vacuum of space and enter Earth's atmosphere?

• they speed up as they enter Earth's atmosphere

• they slow down as they enter Earth's atmosphere

• they continue at the same speed as they enter Earth's atmosphere

• slow down at first and then speed back up

When you go to the movie theater to see a new movie a large video projector at the back of the theater projects the movie onto the big screen. Which statement best describes how you are able to see the movie on the screen at the front?

• projector absorbs light from the room and sends it to the screen

• projector sends light to the screen, which refracts the light into images

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

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

An earthquake produces seismic waves, a type of mechanical wave. The wave begins in the tectonic plates within the Earth's crust beneath the ocean, and then travels through the ocean. What would describe the movement of the wave as it moves from Earth's crust to the ocean?

• the wave stops

• the wave moves faster

• the wave moves slower

• the wave goes the same speed
