Light waves carry [ ] from one place to another.

Answer explanation

Light waves carry energy from place to place. If a material absorbs the light, the material also absorbs the energy.

Why does UV light change the solar beads when light from our class does not?

• Because the solar beads can take in energy from the sun, but not the class lights.

• Because sunlight pulls energy out from the solar beads and the class lights does not.

• Because the sun gives off a type of light that carries energy, and light from the class does not.

• Because light from the sun carries color molecules, and light for the class does not.

Solar panel reflects microwave light. Solar panels transmits radio light. Solar panels absorb visible light. Which type of light is more likely to increase electrical energy?

• The visible light can cause the solar panel to increase electrical energy.

• The microwave light can cause the solar panel to increase electrical energy.

• The radio light can cause the solar panel to increase electrical energy.

• Any of these types of light can cause the marble to get warm, because all light carries energy that can cause materials to change.

Alex has a type of rock called calcite, that sometimes glows. He puts the calcite under a desk lamp but the calcite does not glow. Then he puts it under an ultraviolet lamp and the calcite glows. Why does ultraviolet light make the calcite glow when light from the desk lamp does not?

• Because ultraviolet light carries energy, and light from the desk lamp does not.

• Because ultraviolet light pulls energy out of the calcite, and light from the desk lamp does not.

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

• Because ultraviolet light carries glowing molecules, and light from the desk lamp does not.

Based on this information, which type of light is more likely to damage the material?

• The gamma ray light is more likely to damage the material because the gamma ray light can pull energy out of the material when it passes through the material.

• The X-ray light is more likely to damage the material because the X-ray light bounces off of the material, which means that it has more energy.

• There is no way to know because they are two different types of light, and different types of light can change a material in different ways.

• Neither type of light is likely to damage the material because the material does not take in energy from either the X-ray light or the gamma ray light.

Omar has a piece of rock called quartz. He wonders whether light can cause the quartz to become warm. The table shows what happens when different types of light hit the quartz. Based on this information, which type of light is more likely to cause the quartz to become warm?

• The visible light can cause the quartz to become warm because the visible light can pull energy out of the quartz when it passes through the quartz.

• The infrared light can cause the quartz to become warm because the infrared light bounces off the quartz, which means that it has more energy.

• There is no way to know because they are two different types of light, and different types of light can change a material in different ways.

• Neither type of light can cause the quartz to become warm because the quartz does not take in energy from either the infrared light or the visible light.

Based on this information, which type of light might cause the glass to melt?

• The infrared light can cause the glass to melt.

• The yellow light can cause the glass to melt.

• The X-ray light can cause the glass to melt.The X-ray light can cause the glass to melt.

• Any of these types of light can cause the glass to melt, because all light carries energy that can cause materials to change.
