Vedclass · Answer

(D) The Doppler effect for sound waves depends on the medium. The formula is given by $f' = f \left( \frac{v \pm v_o}{v \mp v_s} \right)$,where $v$ is the speed of sound in the medium,$v_o$ is the speed of the observer,and $v_s$ is the speed of the source.Because the medium provides a preferred frame of reference,the effect is not symmetric with respect to the source and the observer. Therefore,the Assertion is incorrect.The motion of a source relative to a stationary observer is physically different from the motion of an observer relative to a stationary source because the medium is stationary in one case and moving relative to the observer in the other. Thus,the Reason is correct.

$Assertion :$ The Doppler formula for sound waves is symmetric with respect to the speed of the source and the speed of the observer.
$Reason :$ The motion of a source with respect to a stationary observer is not equivalent to the motion of an observer with respect to a stationary source.

$A$ vehicle with a horn of frequency $n$ is moving with a velocity of $30\, m/s$ in a direction perpendicular to the straight line joining the observer and the vehicle. The observer perceives the sound to have a frequency $n + n_1$. Then (if the sound velocity in air is $300\, m/s$):

Obtain the equation of frequency observed by a moving observer and a stationary source.

$A$ train whistling at a constant frequency is moving towards a station at a constant speed $V_S$. The train goes past a stationary observer on the station. The frequency $n'$ of the sound as heard by the observer is plotted as a function of time $t$. Identify the expected curve.

The velocity of sound is $340 \,m/s$. $A$ source of sound having a frequency of $90 \,Hz$ is moving towards a stationary observer with a speed of one-tenth that of sound. The apparent frequency of sound as heard by the observer is: (in $\,Hz$)

$A$ whistle of frequency $540 Hz$ rotates in a horizontal circle of radius $2 m$ at an angular speed of $15 rad/s$. What is the highest frequency heard by a listener at rest with respect to the center of the circle (in $Hz$)? (Velocity of sound in air $= 330 m/s$)
