When a string is divided into three segments of length $l_1,\,l_2$ and $l_3,$ the fundamental frequencies of these three segments are $v_1,\,v_2$ and $v_3$ respectively. The original fundamental frequency $(v)$ of the string is
$\frac{1}{v} = \frac{1}{{{v_1}}} + \frac{1}{{{v_2}}} + \frac{1}{{{v_3}}}$
$\frac{1}{{\sqrt v }} = \frac{1}{{\sqrt {{v_1}} }} + \frac{1}{{\sqrt {{v_2}} }} + \frac{1}{{\sqrt {{v_3}} }}$
$\sqrt v = \sqrt {{v_1}} + \sqrt {{v_2}} + \sqrt {{v_3}} $
$v = v_1 + v_2 + v_3$
A string $1\,m$ long is drawn by a $300\,Hz$ vibrator attached to its end. The string vibrates in three segments. The speed of transverse waves in the string is equal to ..... $m/s$
A stretched string is divided into three segments of lengths $50\,cm,\,\,40\,cm$ and $10\,cm$ with the help of bridges. Their vibrations will have frequencies in the ratio
A pulse on a string is shown in the figure. $P$ is particle of the string. Then state which of the following is incorrect
Four tuning forks of frequencies $200,201, 204$ and $206\, Hz$ are sounded together. The beat frequency will be
A transverse wave is described by the equation $y = {y_0}\,\sin \,2\pi \left( {ft - \frac{x}{\lambda }} \right)$ . The maximum particle velocity is equal to four times the wave velocity if
