When temperature increases, the frequency of a tuning fork

A

increases

B

decreases

C

remains same

D

increases or decreases depending on the material

Text Solution

Verified by Experts

The correct Answer is:
B
With temperature rise frequency of tuning fork decreases. Because, the elastic properties are modified when temperature is changed also,
`n_1=n_0(1-0.00011t)`
Where `n_t=`frequency at `t^@C,n_0=`frequency at `0^@C`

When temreture increases, the frequency of a tuning fork

To reduce the frequency of a tuning fork –

31 tuning forks are arranged in series in increasing order of frequencies and the frequency of the last tuning fork is 3 times the frequency of the first. If each tuning fork produces 4 beats/second with the preceding one, the frequency of the last tuning fork is

When two tuning forks A and B are sounded together, 4 beats per second are head. The frequency of the fork B is 348 Hz. When one of the prongs of the fork A is filled and sounded with B, the beat frequency increases, then the frequency of the fork A is

16 tuning forks are arranged in increasing order of frequency. Any two consecutive tuning forks when sounded together produce 8 beats per second. If the frequency of last tuning fork is twice that of first, the frequency of first tuning fork is :-

A set of 10 tuning forks is arranged in series of increasing frequency. If each fork gives 3 beats with the preceding one and the last fork has twice the frequency of the first, then frequency of the first tuning fork is

The prongs of the tuning fork are filled a little, the frequency of the tuning fork after filled

The prongs of the tuning fork are filed, then the frequency of the tuning fork after filing will be

The frequecies of tuning forks A and B are respectively 5% more and 3% less than the frequency of tuning fork C. When A and B are sounded together 8 beats/second are heard. Then the frequency of the tuning fork B will be

A tuning fork vibrates at a frequency of 256 Hz . (a) When the air temperature increases, the wavelength of the sound from the tuning fork : (i) increase, (ii) remains the same, (iii) decrease. Why ? (b) If the temperature rises from 0^@ to 20^@ C , what is the change in wavelength ?
