  2. the angle of incidence

  3. Angle B

  4. A wave bends as it crosses a boundary

  5. refraction

  6. Which ray best describes the path of the light reflected from the mirror?

  7. Ray c

  8. What is the amplitude of this wave?

  9. 2 meters

  10. When multiple waves combine to make a wave of smaller amplitude?

  11. Destructive interference

  12. Which graphs has an amplitude of 10 centimeters?

  13. Graph C

  14. Which of the graphs has a period of two seconds?
