Question

What are wavelength , frequency, time period and amplitude of a sound wave ?​?

Answer 1

Answer

Here are the brief explanation as well as definition of all the 4 terminologies :

1) Wavelength

• It is denoted by Greek symbol lambda .
• It reffers to the consecutive distance between two successive rarefaction and compression.
• compression refers to the situation when two waves come closer to each other while their separation is termed as rarefaction.

2)Frequencey

• Number of oscillations per unit time of a wave is termed as its frequency.
• It is denoted by (n).
• It's SI unit is Hertz.

3)Time period

• The time taken by two successive compression as well as rarefaction is termed as its time period.
• It is denoted by T

4)Amplitude

• In simple terms the displacement of the wave from its mean position is termed as its amplitude.
• The loudness of the sound can be considered as the change in its amplitude.

Answer 2

Explanation:

Wavelength:the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

Frequency:the rate at which something occurs over a particular period of time.

Time period:the time taken for one complete cycle of vibration to pass a given point

amplitude:a maximum extent of a vibration

or oscillation,measured from the position of

equilibrium
