  1. Determining wave frequency from a graph

  2. f • Frequency = #of cycles/time • Measured in Hertz (Hz)

  3. 1 cycle = 1 full wave to repeat itself

  4. 3 cycles 2 4 5 6 7 8 9 10 11 12 1 3 Time in seconds

  5. from 0 to 12 seconds 0 2 4 5 6 7 8 9 10 11 12 1 3 Time in seconds

  6. f=3/12 s = ¼ Hz 2 4 5 6 7 8 9 10 11 12 1 3 Time in seconds

  7. Or determine the time for 1 full wave cycle

  8. 1 cycle in 4 seconds= ¼ Hz 0 2 4 5 6 7 8 9 10 11 12 1 3 Time in seconds

  9. Period symbol T • The time for 1 cycle

  10. The period for 1 wave is 4 seconds T=4 2 4 5 6 7 8 9 10 11 12 1 3 Time in seconds

  11. What is the frequency? 8 10 14 20 22 24 0 2 4 6 12 16 18 Time in seconds

  12. ? 0 to 24 seconds 3 cycles 8 10 14 20 22 24 0 2 4 6 12 16 18 Time in seconds

  13. 3/24 s= 1/8 Hz 0 to 24 seconds 3 cycles 8 10 14 20 22 24 0 2 4 6 12 16 18 Time in seconds

  14. OR • Frequency – 1 cycle in x seconds

  15. f=1 cycle in 8 seconds= 1/8 Hz 8 10 14 20 22 24 0 2 4 6 12 16 18 Time in seconds

  16. Quiz yourself

  17. On a piece of paper number 1 through 3 and determine the frequency of the following waves.

  18. #1 f= ? 6 7 8 9 10 0 1 2 3 4 5 11 12 Time seconds

  19. #2 f= ? 18 20 22 22 24 0 2 6 8 10 12 14 16 26 4 Time seconds

  20. #3 f = ? 40 45 50 55 5 20 25 30 35 60 65 70 0 10 15 Time seconds

  21. Check your answers Check your answers

  22. #1 f= 1/8 Hz 6 7 8 9 10 0 1 2 3 4 5 11 12 Time seconds

  23. #2 f= 1/8 Hz 18 20 22 22 24 0 2 6 8 10 12 14 16 26 4 Time seconds

  24. #3 f = 1/20 Hz 40 45 50 55 5 20 25 30 35 60 65 70 0 10 15 Time seconds

  25. How did you do?
