2. Graph of Displacement against Position

3. Graph of Displacement against Position
l is the wavelength

4. Graph of Displacement against Position

5. Graph of Displacement against Position
The maximum displacement from the equilibrium position is called the amplitude

6. Graph of Displacement against Time

7. Graph of Displacement against Time
T is the time period

8. Graph of Displacement against Time
T is the time period
Frequency - number of cycles per second

9. Graph of Displacement against Time
T is the time period
Frequency - number of cycles per second
Frequency - determined by the source

10. Graph of Displacement against Time
T is the time period
Frequency - number of cycles per second
Frequency - determined by the source 1
f = T

11. Relation between f, l and v

12. Relation between f, l and v
The wavelength, l is the distance travelled by the disturbance during one time period

13. Relation between f, l and v
The wavelength, l is the distance travelled by the disturbance during one time period

14. Relation between f, l and v
The wavelength, l is the distance travelled by the disturbance during one time period

15. v = f l Relation between f, l and v
The wavelength, l is the distance travelled by the disturbance during one time period
