Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?

• The speed of light changes as it moves from air to water, causing the light to bend.

• The speed of light remains the same as it moves from air to water, causing the light to reflect.

• The speed of light increases when it enters a different medium, but it doesn’t bend.

• The light bends when it enters water due to its reflection.

Which statement best describes white light?

• Successive pressure variations in the air that vary in amplitude and wavelength.

• An electromagnetic wave that is made up of all colors that allows us to see objects.

• The bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through.

• The bending of a wave as it passes at an angle from one medium to another.

Augusta is curious about how light behaves when it interacts with different materials. She points a laser light at the flat side of a glass block and observes that the light bends as it moves from air into the glass. Which phenomenon is responsible for this bending of light?

• Transmission

• Reflection

• Refraction

• Absorption

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 screen at the front?

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

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

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

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

On a hot summer day two students were playing outside. One was wearing a white shirt while the other was wearing a black shirt. Why was the student who was wearing the black shirt getting hotter than the other student?

• White absorbs all light as heat while black reflects light

• White reflects light while black absorbs all light as heat

• White refracts light while black reflects all light

• The color of the shirt does not matter
