Question

A transverse wave is passing through a medium. The maximum speed of the vibrating particle occurs when the displacement of the particle from the mean position is

• A. zero
• B. half of the amplitude
• C. equal to the amplitude
• D. none of the above

Answer 1

The correct option is A zero

The maximum speed of the vibrating particle is when particle is on mean position.
In general total energy of the system remains constant. At the mean position potential energy is minimum this implies that kinetic energy will be maximum. Hence speed will be maximum.
