Embibe Experts Solutions for Exercise 1: EXERCISE 14.1

A tuning fork has frequency of vibration $200 \mathrm{Hz}$. If velocity of sound in air is $330 \mathrm{m} {\mathrm{s}}^{-1}$, then how far the sound has traversed while tuning fork completes $20$ vibrations?

The transverse wave, propagating through a medium is given by $y=A\cos 2\pi \left[ft-\frac{x}{\lambda }\right].$ If maximum particle velocity of medium is two times the velocity of wave through medium, then

A transverse wave travelling on a taut string is represented by $y=0.01\sin 2\pi (10t-x)$ where $y$ and $x$ are in metre and $t$ is in second. Then

The equation $y=A{\sin }^2(kx-\omega t)$ represents a wave motion with

$y$ versus $x$ graph of a transverse wave propagating through the medium is shown, where $y$ is displacement of particles from their mean position at distance $x$ from the source at $t=0 .$ Select the incorrect statement about particles shown in figure
