Across
- 2. is a common phenomenon that can be explained classically by the superposition of waves.
- 3. inventor of mirror
- 6. (farsightedness)
- 9. refers to various phenomena that occur when a wave encounters an obstacle or opening.
- 10. smooth, shiny surfaces that reflect light and allows us to see an image, or reflection on their surface.
- 13. The ten lettered property of electromagnetic waves. This length is usually specified in meters (m), centimeters (cm) or millimeters (mm).
- 14. radiation, the fluctuations of electric field and magnetic fields
- 15. has a reflecting surface that is curved outward.
- 17. is a mirror with a curved reflecting surface.
- 18. law, another word for law of refraction that states that the ratio of the angles of incidence and transmission is equal to the ration of the refractive index of the materials at interface.
- 19. an electromagnetic radiation/electromagnetic wave that can be detected by the human eye.
Down
- 1. The separation of visible light into its different colors
- 4. (Nearsightedness)
- 5. (also polarisation) is a property applying to transverse waves that specify the geometrical orientation of the oscillations.
- 7. is a mirror with a flat (planar) reflective surface.
- 8. has a reflecting surface that is curved inward.
- 11. The nine lettered property of electromagnetic waves. the number of occurrences of a repeating event per unit of time
- 12. can be thought of as the rate at which an object covers distance.
- 16. are curved pieces of glass or transparent materials that refracts light.
- 19. of reflection, states that the angle of reflection is equal to the angle of incidence.
