MHT CET 2025 23rd April Morning Shift | Waves Question 1 | Physics

A particle performs S.H.M. of amplitude 'A' and wavelength ' $\lambda$ ', Then the velocity of the wave (V) and the maximum particle velocity (v) are related as

$v=\frac{\lambda V}{4 \pi A}$

$\quad V=\frac{\lambda v}{4 \pi A}$

$\quad v=\frac{2 \pi A}{\lambda} v$

$V=\frac{2 \pi A}{\lambda} v$

Two identical straight wires are stretched so as to produce 6 beats per second when vibrating simultaneously with tensions ' $\mathrm{T}_1$ ' and ' $\mathrm{T}_2$ ' respectively. On changing the tension slightly in one of them, the beat frequency remains unchanged. This will happen when (Given $\rightarrow \mathrm{T}_1>\mathrm{T}_2$ )

$\mathrm{T}_1$ is increased or $\mathrm{T}_2$ is decreased

$\mathrm{T}_1$ is increased by 144

$\mathrm{T}_2$ is decreased by 144

$T_1$ is decreased or $T_2$ is increased

Two tuning forks when sounded together produce 4 beats per second. One of the forks is in unison with 23 cm length of sonometer wire and other with 24 cm length of the same wire. The frequencies of the two tuning forks are

$96 \mathrm{~Hz}, 92 \mathrm{~Hz}$

$92 \mathrm{~Hz}, 88 \mathrm{~Hz}$

$72 \mathrm{~Hz}, 68 \mathrm{~Hz}$

$48 \mathrm{~Hz}, 44 \mathrm{~Hz}$
