A boy is walking away from a wall towards an observer at a speed of $1\, metre/sec$ and blows a whistle whose frequency is $680 Hz.$ The number of beats heard by the observer per second is (Velocity of sound in air $= 340\, metres/sec$)
A steel rod $100 cm$ long is clamped at its mid-point. The funda-mental frequency of longitudinal vibrations of the rod is given to be $2.53 kHz$. What is the speed of sound in steel .... $km/s$
Two persons $A$ and $B$, each carrying a source of sound of frequency $n$, are standing a few metres apart in a quiet field. $A$ starts moving towards $B$ with a speed $u$. If $v$ is the speed of sound, the number of beats heard per second by $A$ will be
$5\, beats/ second$ are heard when a turning fork is sounded with a sonometer wire under tension, when the length of the sonometer wire is either $0.95\,m$ or $1\,m$ . The frequency of the fork will be ... $Hz$
A standing wave having $3$ nodes and $2$ antinodes is formed between two atoms having a distance $1.21\;\mathring A$ between them. The wavelength of the standing wave is .... $\mathop A\limits^o $
A source and an observer approach each other with same velocity $50 m/s$. If the apparent frequency is $435 \,s^{-1}$, then the real frequency is .... $s^{-1}$
A student is experimenting with resonance tube apparatus in Physics lab to find the speed of sound at room temperature. He got first two resonating lengths of air column as $17\, cm$ and $51 \,cm$, using tuning fork of frequency $512\, Hz$. Find speed of sound at room temperature ..... $m/s$
