Statement I: A tuning fork is considered as a source of an acoustic wave of a single frequency as marked on its body. Statement II: The tuning fork cannot produce any of its harmonics due to its special nature of construction.

A

Statement I is true, Statement II is true: Statement II is a correct explanation for statement I.

B

Statement I is true, Statement II is true, Statement II is NOT a correct explanation for Statement I.

C

Statement I is true, Statement II is false

D

Statement I is falce: Statement II is true

Text Solution

Verified by Experts

The correct Answer is:
A
The tuning fork does produce harmonics, but the intensities of the harmonics are too weak to be effective, due to its special ditribution of mass and the use of prongs.

Statement I: A body weighs less on a hill top than on earth's surface even though its mass remains unchanged. Statement II: The acceleration due to gravity of the earth decreases with height.

A source of sound with adjustable frequency produces 2. beats per second with a tuning fork when its frequency is either 476 Hz or 480 Hz. What is the frequency of the tuning fork ?

Two tuning forks when sounded together give 8 beats per second. When tuning fork A is sounded with air column of length 37.5 cm closed at one end, resonance occurs in its fundamental mode. Tuning fork B gives resonance with air column of length 38.5 cm and is closed at one end in its fundamental mode. Find the frequencies of tuning forks.

Statement 1: A tuning fork of constant frequency sends sound waves in air. If temperature of the air increases, then the wavelength of sound wave in air decreases. Statement 2: Speed of sound in air increases with increases in temperature of air
