- 2A siren placed at a railway platform is emitting sound of frequency $5 kHz$. A passenger sitting in a moving train $A$ records a frequency of $5.5 kHz$ while the train approaches the siren. During his return journey in a different train $B$ he records a frequency of $6.0 kHz$ while approaching the same siren. The ratio of the velocity of train $B$ to that of train $A$ isView Solution
- 3In an organ pipe whose one end is at $x = 0$, the pressure is expressed by $p = {p_0}\cos \frac{{3\pi x}}{2} \,\,sin\,\, 300\pi t$ where $x$ is in meter and $t$ in $sec$. The organ pipe can beView Solution
- 4You are driving in your car listening to music on the radio. Your car is equipped with radio that can recieved radio singals of frequency $(f_1 \approx\, 3\, MHz),$ other of frequency $(f_2 \approx\, 30\, MHz),$ and third of frequency $(f_3 =\, 3\, GHz),$. You enter a tunnel with a circular opening of diameter $10\ m.$ Which kind of radio signal will you be able to receive the longest as you continue to travel in the tunnel ?View Solution
- 5First overtone frequency of a closed organ pipe is equal to the first overtone frequency of an open organ pipe. Further nth harmonic of closed organ pipe is also equal to the mth harmonic of open pipe, where $n$ and $m$ are:View Solution
- 6$S_1$ and $S_2$ are two identical sound sources of frequency $656 \ Hz$. The source $S_1$ is located at $O$ and $S_2$ moves anti$-$clockwise with a uniform speed $4 \sqrt{2} \ ms ^{-1}$ on a circular path around $O$, as shown in the figure. There are three points $P, Q$ and $R$ on this path such that $P$ and $R$ are diametrically opposite while $Q$ is equidistant from them. A sound detector is placed at point $P$. The source $S_1$ can move along direction $O P.[$Given: The speed of sound in air is $324 \ ms ^{-1} ]$View Solution
$(1)$ When only $S_2$ is emitting sound and it is $Q$, the frequency of sound measured by the detector in $Hz$ is $. . . . .$
$(2)$ Consider both sources emitting sound. When $S_2$ is at $R$ and $S_1$ approaches the detector with a speed $4 \ ms ^{-1}$, the beat frequency measured by the detector is $Hz$.
- 7A vibrating string of certain length $l$ under a tension $T$ resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length $75\, cm$ inside a tube closed at one end. The string also generates $4\, beats$ per second when excited along with a tuning fork of frequency $n$. Now when the tension of the string is slightly increased the number of beats reduces to $2\, per second$. Assuming the velocity of sound in air to be $340\, m/s$, the frequency $n$ of the tuning fork in $Hz$ isView Solution
- 8$Assertion :$ The base of Laplace correction was that exchange of heat between the region of compression and rarefaction in air is negligible.View Solution
$Reason :$ Air is bad conductor of heat and velocity of sound in air is quite large. - 9For a certain organ pipe, three successive resonance frequencies are observed at $425,595,$ and $765 \,Hz$ respectively, Taking the speed of sound in air to be $340 \,m / s$ the fundamental frequency of the pipe (in $Hz$ ) is .........View Solution
