Across
- 5. mirroring
- 7. vascular layer of the eye
- 8. occurs where rays converge

- 11. the reflective surface bulges toward the light source
- 13. controls the amount of light that enters the eye
- 14. two waves superpose to form same amplitude
- 15. relationship between angles of incidence and refraction

- 18. allows objects to be seen clearly through it
Down
- 1. the intersection of a line
- 2. transparent part of the eye
- 3. when a wave encounters an obstacle or a slit
- 4. reflecting surface that is recessed inward
- 6. a hole or an opening through which light travels
