To study the relation between frequency and length of a given wire under constant tension using a sonometer.

1) What is meant by the superposition of waves?

The intermixing of two or more waves to generate a new wave is known as the superposition of waves.

2) What is meant by the superposition principle?

The superposition principle states that the resultant quantity is equal to the vector total of the individual quantities of superposing entities.

3) What is meant by stationary waves?

The superposition of two moving waves of the same amplitude and frequency with the same velocity in opposite directions generates stationary waves.

4) State the law of length.

The frequency of the vibrating string changes inversely as its length varies if mass per unit length and tension is constant.

5) State the law of tension.

The frequency of the vibrating string changes directly as the square root of the string’s tension if its mass per unit length and length remain constant.

6) State the Law of mass.

The frequency of the vibrating string changes inversely as the square root of the string’s mass per unit length if its tension and length remain constant.

7) What is meant by free vibrations?

Vibrations of a vibrating object sustained by the object itself are known as free vibrations.

8) What is meant by forced vibrations?

Vibrations of a vibrating object under constant force are known as force vibrations.

9) What is meant by resonant vibrations?

Vibrations of a vibrating object under the influence of another vibrating object of the same frequency (at close proximity) are known as resonant vibrations.

10) Can sound travel through a vacuum?

No, a physical medium is necessary for the propagation of sound.

11) What is the audible frequency range for human beings?

The audible frequency range for human beings is between 20 Hz and 20,000 Hz.

12) What types of waves are light waves and sound waves?

Light is a transverse wave, and sound is a longitudinal wave.

13) What types of waves are produced in a sonometer wire?

Waves generated in a sonometer wire can be transverse or stationary.

14) What is a sonometer?

A sonometer is a device used to calculate the frequency of a vibrating object producing sound.

15) What is meant by a transverse wave?

When the wave’s propagation direction is perpendicular to the orientation of vibration of the medium’s particles, then the wave is known as a transverse wave.

16) Define node.

In a stationary wave, the place where there is zero amplitude is known as a node.

17) Define antinode.

In a stationary wave, the place where there is maximum amplitude is known as an antinode.

18) What are overtones?

They are the notes which possess frequencies of basic multiples of the fundamental notes.

19) What is a pitch?

Pitch is a property of a sound that distinguishes a dull sound from a sharp sound.
