For 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 .........
Two strings $X$ and $Y$ of a sitar produce a beat frequency $4 Hz$. When the tension of the string $Y$ is slightly increased the beat frequency is found to be $2 Hz.$ If the frequency of $X$ is $300 Hz,$ then the original frequency of $Y$ was .... $Hz$
Source and observer both start moving simultaneously from origin, one along $x-$axis and the other along $y-$axis with speed of source = twice the speed of observer. The graph between the apparent frequency observed by observer $f$ and time $t$ would approximately be :
The superposing waves are represented by the following equations :${y_1} = 5\sin 2\pi (10\,t - 0.1x)$, ${y_2} = 10\sin 2\pi (20\,t - 0.2x)$ Ratio of intensities $\frac{{{I_{\max }}}}{{{I_{\min }}}}$ will be
A toy-car, blowing its horn, is moving with a steady speed of $5\, m/s$ , away from a wall. An observer, towards whom the toy car is moving, is able to hear $5\, beats$ per second. If the velocity of sound in air is $340\, m/s$, the frequency of the horn of the toy car is close to ... $Hz$
A travelling wave is partly reflected and partly transmitted from a rigid boundary. Let $a_i, a_r$ and $a_t$ be the amplitude of incident wave, reflected wave and transmitted wave and $I_i, I_r$ and $I_t$ be the corresponding intensities. Then choose the correct alternatives
A string is stretched between fixed points separated by $75.0\, cm$. It is observed to have resonant frequencies of $420\, Hz$ and $315\, Hz$. There are no other resonant frequencies between these two. Then, the lowest resonant frequency for this string is .... $Hz$
The fundamental frequency of a sonometer wire increases by $6$ $Hz$ if its tension is increased by $44\%$ keeping the length constant. The change in the fundamental frequency of the sonometer wire in $Hz$ when the length of the wire is increased by $20\%$, keeping the original tension in the wire will be :-
A person driving car at a constant speed of $15\,m / s$ is approaching a vertical wall. The person notices a change of $40\,Hz$ in the frequency of his car's horn upon reflection from the wall. The frequency of horn is ............ $Hz$. (Given : Speed of sound : $330\,m / s$ )
A tuning fork of frequency $480 Hz$ produces $10$ beats per second when sounded with a vibrating sonometer string. What must have been the frequency of the string if a slight increase in tension produces lesser beats per second than before ..... $Hz$
