Q2 of 97 Page 322

A sine wave is travelling in a medium. A particular particle has zero displacement at a certain instant. The particle closest to it having zero displacement is at a distance

A sine waves has both maxima and a minima and the particle displacement has phase difference


of radians. Therefore, on similar grounds we can make a claim that If a particle displacement x


is zero at a given point in time, the particle is closest to having a zero displacement is at a distance


equal to
