What happens to the wavelength of light as it passes from water to air?

• It decreases
• It increases
• It doubles
• It stays the same

If you put a pencil in a cup of water, it looks as if it is broken and larger in the water. This is because light waves....

• can reflect off the surface
• are absorbed instead of reflected
• bend when passing from air to water
• wrap around a barrier, like the pencil

Light can behave differently as it strikes a variety of surfaces. Three behaviors of light are shown here as ray diagrams. Which three behaviors are shown?

• reflection, scattering, absorption
• scattering, diffraction, transmission
• reflection, absorption, transmission
• reflection, refraction, absorption

The speed of light was recorded as it passed through different media. The light passed through air, water, and glass. According to the graph, light waves travel....

• faster in glass than in water
• faster in air than in water
• faster in water than in air
• faster in glass than in air

If a wave has a greater frequency, what happens to wavelength?

• Wavelength will increase
• Wavelength decreases
• Wavelength stays the same

What is a ray diagram used for?

• to measure the amplitude of waves
• to calculate the frequency
• to show the direction of wave energy
• to illustrate the possible pathways light can take

Which of the following is an example of wave transmission?

• A flashlight beam passing through a glass window
• A sound wave bouncing off a wall
• A light wave being absorbed by black paper
• A light wave reflecting off a mirror
