Question

Define amplitude, frequency and time period of vibration.

Answer 1

1. Amplitude: It defines the loudness of sound whether the sound is loud or soft.
   Amplitude is also directly related the energy of the sound, louder the sound greater is the energy it carries.
   Higher the amplitude louder the sound; lower the amplitude softer is the sound.
2. Frequency-it is defined as the number of oscillations or vibrations that occur in one second.
   Its measured in hertz (Hz).
3. Time period-It is the time taken by the wave to complete one oscillation; denoted by T and measured in seconds.
