2 How Do Waves,

2. A guitar string is plucked and begins moving back and forth before sound is heard. What motion produced the sound?
5. An astronaut cannot hear another astronaut speaking outside a spacecraft because there is no matter to carry the vibrations. Which type of wave is missing?
7. A clear window allows sunlight to pass into a classroom instead of blocking it. Which wave behavior is occurring?
8. A scientist compares radio waves, visible light, and X-rays as different forms of the same type of energy. What complete range is being studied?
11. A pebble is dropped into a pond, and ripples spread outward while the water mostly stays in place. What is moving across the pond?
12. A mosquito makes a much higher sound than a drum because its waves occur more times each second. Which wave property is greater?
13. A prism separates sunlight into the colors of a rainbow. Which part of the electromagnetic spectrum is being separated?
14. A straw appears bent when viewed through a glass of water because light changes speed between air and water. Which wave behavior explains this observation?
15. Two tuning forks produce different notes because one vibrates more times each second than the other. Which sound property changes?

1. A black shirt becomes warmer than a white shirt in sunlight because it takes in more light energy. Which wave interaction explains this?
3. Ocean waves are spread farther apart as they travel across the water. Which wave property has increased?
4. Sunlight reaches Earth after traveling through the nearly empty vacuum of space. Which type of wave made this journey?
6. A speaker is turned up much louder, causing the sound waves to carry more energy. Which wave property increased?
9. Scientists detect energy traveling through Earth's interior after an earthquake. What type of wave are they measuring?
10. A flashlight shines onto a mirror, and the light changes direction without entering the mirror. Which wave behavior occurred?
