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

Open in App Solution

**Wavelength:**

The distance traveled by the wave during one complete oscillation is called the wavelength of the wave.

The SI unit of wavelength is a meter(m).

**Frequency:**

The number of oscillations made by the wave in one second is called the frequency of the wave.

It is measured in hertz(Hz).

**Time period:**

The time taken by the wave to complete one oscillation is called the amplitude of the wave.

Unit of time period is

S

**Amplitude:**

The maximum displacement of the wave from its mean or equilibrium position is called the amplitude of the wave.

Unit of amplitude is

**Amplitude :**It is defined as the maximum displacement produced in the vibrating particle on either side of the mean position. It is denoted by A. Its SI unit is metre.

**Wavelength :**It is defined as the distance travelled by a wave during the time a particle of the medium completes one vibration. It is denoted by k. Its SI unit is metre.

Frequency: It is the number of occurrences of a repeating event per unit of time. Its SI unit is Hertz (Hz).

**Hint:**For any vibrating particle, the term amplitude means the maximum displacement from the mean position, the wavelength is the distance travelled in a complete vibration. Similarly, the frequency is the number of complete vibrations per second.

**Complete answer:**

For any particle that is moving in a periodic motion, that parameters of its motion can be determined by a few common terms. They are the amplitude, frequency, and the wavelength.

A) **Amplitude:** The amplitude of any periodic motion is the maximum displacement that a particle suffers from the initial position during the vibration. It is denoted by the letter A and has the dimension of length.

B) **Wavelength:** Wavelength of a wave is the distance between two similar points in a wave. For example, wavelength of a wave can be taken as the distance between two peaks or two troughs in a wave. It is denoted by

λ λ

and has the dimension of length.

C) **Frequency:** The number of complete vibrations that a particle performs per second is called the frequency of the vibration. It is denoted by the letter

f f

and has the dimension of time inverse and the SI the unit of frequency is given by Hertz (Hz). The frequency is related to the wavelength as,

f= v λ f=vλ where v v

is the speed of the wave.

**Note:**

A few examples of the periodic motion are the simple harmonic motion like the motion of a pendulum or the vibration of atoms about their mean position. We can calculate the various parameters from their equations.
