1. Wavelength: The distance travelled by the wave during one complete oscillation is called wavelength of the wave.
2. Frequency: The number of oscillations made by the wave in one second is called the frequency of the wave.
3. Time period: The time taken by the wave to complete one oscillation is called the amplitude of the wave.
4. amplitude: The maximum dis-placement of the wave from its mean or equilibrium position is called the amplitude of the wave.
