25 Questions

1. A wave that moves along the medium.

2. The smooth curved surface at the back of the eye - where the lens of the eye projects an image. It then converts the light to electrical impulses

3. The dark circular spot in the middle of the iris of the eye. The pupil admits light into the eye.

4. The fixed points on a standing wave

5. Range of wavelengths humans can see

6. The nerve that relays information from the eye to the brain.

7. A wave that does not travel; the superposition of two waves traveling in opposite directions

8. A wave in which the motion of particles in the medium is at right angles to the motion of the wave itself.

9. Another word for an S wave; transverse seismic wave.

10. The bottom or pit of a transverse wave or water wave.

11. The interaction of two or more waves that displace the medium in the same way. The overlap of the maximum displacement points in each wave creates a maximum total displacement.

12. The angle of incidence is equal to the angle of reflection.

13. Interference in time

14. The change in direction of a propagating wave (light or sound) when passing from one medium to another

15. Speed = wavelength x frequency

16. Speed of sound in air

17. The reflection of light primarily in one direction - as from a mirror.

18. The energy in a wave is proportional to the square of the amplitude

19. Boundary in which the end of the wave medium is fixed: not free to move.

20. A transparent outer layer of the eye that covers the iris and pupil. The cornea acts like a lens.

21. An oscillation of electric and magnetic fields that may propagate through a vacuum or through a medium

22. The relationship between sound speed and medium temperature

23. The return of a wave from a surface.

24. Arriving or incoming. An incident ray of light may give rise to a reflected ray and a refracted ray.

25. Media of Pure Transverse Waves
