What is amplitude of wave?
- Amplitude of wave is the maximum vertical displacement of a particle from its position.
- Amplitude defines the loudness of sound.
- If the amplitude is high, the loudness is also high.
What is Frequency of wave?
- Frequency of a wave is the reciprocal of time taken by the wave to complete one oscillation.
- It determines the pitch of wave.
- If the frequency is high, pitch of the sound is also high.
