B
Frequency
b (b) Frequency of a wave is characterised by the source of the wave, which produces disturbance, therefore it doesn't change when medium is changed. So it doesn't matter whether sound is in air or material of tuning fork, frequency will not change.

A transverse wave of frequency $500 \,Hz$ and speed $100 \,m / s$ is travelling in the positive $x$-direction on a long string. At time $t=0 \,s$, the displacements at $x=0.0 \,m$ and at $x=0.25 \,m$ are $0.0 \,m$ and $0.02 \,m$, respectively. The displacement at $x=0.2 \,m$ at $t=5 \times 10^{-4} s$ is ............ $m$
The frequencies of two sound sources are $256 Hz$ and $260 Hz$. At $t = 0,$ the intensity of sound is maximum. Then the phase difference at the time $t = \frac{1}{16}\, sec$ will be
An observer moves towards a stationary source of sound with a speed $1/5^{th}$ of the speed of sound. The wavelength and frequency of the source emitted are $\lambda $ and $f$ respectively. The apparent frequency and wavelength recorded by the observer are respectively
A steel rod $100\, cm$ long is damped at into middle. The fundamental frequency of longitudinal vibrations of the rod are given to be $2.53\, kHz$. What is the speed of sound in sound is steel ? (in $km/s$)
In a gultar, two strings $A$ and $B$ made of same materlal are slightly out of tune and produce beats of frequency $6\, Hz$. When tension in $B$ is slightly decreased, the beat frequency increases to $7 \,Hz$. If the frequency of $A$ is $530\, Hz ,$ the orlginal frequency of $B$ will be $.........Hz$
