WAVEFRONTA line of surface which joins all points which have the same displacement at the same moment (they are all in phase).
The perpendicular distance between two wavefronts represents one wavelength.
Plane wavefront & Circular wavefront
Amplitudes- The distance from the maximum displacement to the equillibrium position is called the Amplitudes, a.
- SI unit : meter, m
- Loud sounds have a large amplitude.
- Brightness in light have a large amplitude.
The distance between two adjacent point of the same phase of waves.
- The times taken for the system make a complete oscillation is known as Period, T.
- The number of complete oscillations made by a system in one second is called frequency, f.
The relationship between wavelength, frequency and speed of wave is:
