When the antinodes are all at their extreme displacements, the energy stored is:
Correct answer: C. P.E
- A. K.E
- B. Thermal energy
- C. P.E
- D. All of these
Explanation
At the extreme position the speed is zero so the kinetic energy will also be zero as K.E = 1/2 x m x v2. Whereas the potential energy will be max as the string is also on maximum height. So, the total energy will be in the form of potential energy. P.E = mgh.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
