Two wave pulses identical in shape but inverted with respect to each other are produced at the two ends of a stretched string.

Question 1

Two wave pulses identical in shape but inverted with respect to each other are produced at the two ends of a stretched string. At an instant when the pulses reach the middle, the string becomes completely straight. What happens to the energy of the two pulses?

Question 2

When the pulses reach the middle, though the string becomes completely straight, the particles of the string there do not stop but have speed. Due to the speed, the pulses again emerge out after a few moments. So the energy of the two pulses at the middle is in the form of kinetic energy of the particles.
