What are wavelength, frequency, time period and amplitude of a sound wave?
Answers
Answer:
(a) Wavelength – Wavelength can be defined as the distance between two consecutive rarefactions or two consecutive compressions. The SI unit of wavelength is meter (m).
(b) Frequency – Frequency is defined as the number of oscillations per second. The SI unit of frequency is hertz (Hz).
(c) Amplitude – Amplitude can be defined as the maximum height reached by the trough or crest
of a sound wave.
(d) Time period – The time period is defined as the time required to produce one complete cycle of a sound wave.

Answer:
Explanation:
Wavelength=the distance between two crests and troughs of wave.
frequency=the no. of sound waves produced in 1 second.
time period=time period is taken to produce one wave of sound.
amplitude =maximum displacement along the mean position of particles of medium.
