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
31 2 4 56789101112 Time in seconds 3 cycles

5
from 0 to 12 seconds 31 2 4 56789101112 Time in seconds 0

6
f=3 s = ¼ Hz 31 2 4 56789101112 Time in seconds

7
Or determine the time for 1 full wave cycle

8
1 cycle in 4 seconds= ¼ Hz 31 256789101112 Time in seconds 04

9
Period symbol T The time for 1 cycle

10
The period for 1 wave is 4 seconds T=4 31 2 4 56789101112 Time in seconds

11
What is the frequency? 0246 810 12 14 16 18 20 Time in seconds 2224

12
? 0246 810 12 14 16 18 20 Time in seconds 2224 3 cycles 0 to 24 seconds

13
0246 810 12 14 16 18 20 Time in seconds 2224 3 cycles 0 to 24 seconds 3/24 s= 1/8 Hz

14
OR Frequency – 1 cycle in x seconds

15
f=1 cycle in 8 seconds= 1/8 Hz 0246 810 12 14 16 18 20 Time in seconds 2224

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

18
#1 f= ? 0 12 34 5 678910 1112 Time seconds

19
#2 f= ? Time seconds 02 4 6 81012 1416 18 2022 24 26

20
#3 f = ? 0 5 1015 20 2530 35 40455055 606570 Time seconds

21
Check your answers

22
#1 f= 1/8 Hz 0 12 34 5 67910 1112 Time seconds 8

23
#2 f= 1/8 Hz Time seconds 02 4 6 1012 1416 18 2022 24 268

24
#3 f = 1/20 Hz 0 5 1015 2530 35 40455055 606570 Time seconds 20
