If you take snapshots of a standing wave on a string, there are certain instants when the string is totally flat. What has happened to the energy of the wave at those instants?

Short Answer

Expert verified

All the energy at those instants is in the form of Kinetic energy.

Step by step solution

01

Description of Energy

Total energy can be expressed as sum of potential and kinetic energy.

02

Energy at mean position

We know that at mean positions maximum energy of the system exists in the form of kinetic energy. Therefore at these instants when the string goes flat (all particles of the string are in their mean positions), maximum energy exists in the form of kinetic energy in the string.
