End of Unit Test Light Waves

When a car sits in the sun for a long time, will the paint be damaged by the sun?

• yes, the paint absorbs energy, causing damage

• yes, the sun can pull energy out of the paint, damaging it

• no, light only warms things up, not damages it

• no, a physical thing like like can;t change any other physical things like paint on a car

Carson has a calcite rock. He put it under an ultraviolet light, and the rock glows, but when he puts it under a regular desk lamp, the rock doesn't change. How is this so?

• no, the calcite doesn't change at all

• the calcite can take in energy from the desk lamp, but not the ultraviolet light

• the calcite can take in energy from the ultraviolet light, but not the desk lamp

• the ultraviolet light pulls energy out of the rock, and the desk lamp doesn't

If x-ray light is reflected off a material, and a gamma ray is reflected off of the same material, which type of light damages the material more?

• both the types of light

• no one knows because the light doesn't change

• the gamma ray light is more likely to damage hat material because it is a stronger type of light and more vibrant

• neither the two because a material must absorb energy for it to be damaged

Ava is talking about a certain "invisible ink" pen that she got for her birthday. She says that when it is out in the sun, you can see the writing, but if it isn't in the sun's light, you can't see the writing. Is this possible?

• no, light only warms things up, not damages it

• no, physical things can't change

• yes, the ink takes in light from the sun, causing it to become visible to the human eye

• yes, the sun pulls out all the energy in the ink, causing it to become visible

Kavya observes that when shining her desk lamp on a mirror, nothing changes. When she shines an infrared light on the same mirror, the mirror gets warmer. How is this so?

• the mirror takes in energy from the infrared lamp, and not the desk lamp making it warmer

• the infrared light carries heat molecules and the desk lamp doesn't

• the infrared light carries actual energy, and the desk lamp doesn't

• the desk lamp pulls out energy from the mirror

Aria is observing a piece of quartz she found in her backyard. She wonders if infrared light, or visible light can make the rock warmer. Since infrared light reflects off of the quartz and visible light is transmitted through the rock, which type of light causes the rock to change?

• the visible light because it pulls energy out of the quartz

• the infrared light because it reflects off of the rock

• there is no way to know because the light doesn't change

• neither types of light can cause the rock to get warmer because the quartz doesn't take in energy from any of the two types of light

Sam found a special kind of paper that changes color outside in the sun. Is this true?

• yes, light from the sun causes the paper to loose energy

• yes, the paper takes in energy from the sun, causing it to change

• no, everyone knows that this statement is false

• no, light only warms objects

Hajar has a toy that is painted yellow, and when she observes it under a desk lamp, it doesn't change. But, when she puts it under an infrared lamp the toy turns blue. How is this so?

• the desk lamp carries heat molecules and light waves; the infrared light doesn't

• infrared light pulls energy out of the paint

• the paint can absorb energy from the infrared light but not the desk lamp

• the infrared light carries heat molecules and light waves; the desk lamp doesn't

Sebastian is experimenting with lasers and light waves. He observes that a helium-neon laser is reflected off silicone, a carbon dioxide laser is absorbed by the silicone, and the diode laser transmits through silicone. Which laser can cut a hole through the material?

• the helium-neon laser because it is reflected off the material

• the carbon dioxide laser because it is absorbed by the material

• the diode laser because it transmits through the material

Rebecca says that there is a type of glue that when it is put under a certain type of light, it dries. Can light cause glue to dry?

• no, light only warms things up

• yes, light can take in energy from the light making it dry

• yes, light pulls energy out the of the glue, making it dry

• no, physical things like light can't change physical materials
