Question

The loudness of sound produced by tuning fork can be Increased by increasing?

• A. Wavelength
• B. Pitch
• C. Amplitude
• D. Frequency

Answer 1

The correct option is C

Amplitude

Explanation of the correct option:

Option C:

1. Amplitude is the character of the sound wave which determines the loudness.
2. Amplitude is the maximum displacement of the particle from its mean position.
3. So if we are going to increase the amplitude of the tuning fork the louder the sound produced.

Explanation of incorrect options:

Option A:

1. Wavelength is the character of the sound wave which is determined by the length of the wave travelled between one compression or rarefaction.

Option B:

1. Pitch is the characteristic of the sound that determines the shrillness or the flatness of the sound.

Option D:

1. Frequency of the sound wave determines the number of waves produced per second.

Hence, option (C) is the correct answer.
