Across
- 3. light passes through an object but is scattered so an image is blurred
- 7. what is measured in a wave's period
- 10. waves that can travel through space
- 12. What Herschel used to measure the differences between light waves
- 13. need a medium to travel though
- 15. smallest wave length, highest frequency
Down
- 1. the type of wave that is created when you increase the frequency and decrease the wave length of visible light
- 2. waves that we can see
- 4. type of interference when a crest and a trough from wave meet
- 5. a change in frequency caused by an objects movement
- 6. light bounces off the material and cannot go through
- 8. the property of sound waves that an ultrasound uses to create an image
- 9. the part of a standing wave where the wave comes to rest
- 11. waves with the longest wavelength and the lowest frequency
- 14. waves that travel along the top of a medium
