Across
- 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?
Down
- 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?
