Across
- 1. When energy from a wave passes through an object
- 3. The bouncing back of a wave when it hits a surface through which it cannot pass.
- 5. Allowing light to pass through (like glass)
- 6. The transfer of energy carried by light waves to particles of matter. Radiant energy must be absorbed before it can be transformed into other forms.
- 7. The angle of incidence is equal to the angle of reflection
- 10. Blocks all light (like wood)
- 13. All waves in the EM spectrum travel at this speed
- 14. The part of the electromagnetic spectrum that consists of waves detectable by the human eye (ROYGBIV) and appears as "white" light
- 15. A lens or mirror that is curved outwards
- 17. The curving of a wave as it moves around an obstacle or passes through a narrow opening
- 19. A type of wave, such as a light wave or radio wave, that does not require a medium to travel
Down
- 2. The release of light energy by particles of matter that have absorbed energy
- 4. Semitransparent - allows some light to pass through (like wax paper)
- 8. A curved transparent object that refracts light
- 9. The range of all EM waves (RMIVUXG) that travel at the same speed but differ in wavelength and frequency
- 11. A lens or mirror that is curved inwards
- 12. A piece of glass that separates white light into its 7 colors
- 16. An opaque surface that reflects light
- 18. Bending of a wave as it passes at an angle from one medium to another due to change in wave speed
