- 6. (3 words) this phenomenon takes place at or greater than a certain angle whereby refraction can no longer occur
- 9. the part of the eye that is tissue sensitive to light
- 11. when a light ray exits a more dense medium (e.g., a glass block) to a less dense block, it bends ____ from the normal
- 12. a wave where the displacement is parallel to the direction the wave is travelling
Down
- 1. the term used to describe light of one specific colour or wavelength
- 2. the distance between successive crests of a wave
- 3. the maximum displacement (e.g., a crest or a trough) of a transverse wave
