Question
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
Options
\[\lambda/4\]
\[\lambda/3\]
\[\lambda/2\]
\[\lambda\]
Solution
\[\lambda/2\]
A sine wave has a maxima and a minima and the particle displacement has phase difference of π radians. Therefore, applying similar argument we can say that if a particular particle has zero displacement at a certain instant, then the particle closest to it having zero displacement is at a distance is equal to
\[\lambda/2\]
