Question
A progressive wave is travelling in a string as shown. Then which of the following statement about KE and potential energy of the elements A and B is true?
Options
A.For point A : kinetic energy is maximum and potential energy is min.
B.For point B : kinetic energy is minimum and potential energy is min.
C.For point A : kinetic energy is minimum and potential energy is max.
D.For point B : kinetic energy is minimum and potential energy is max.
Solution
Sol. 
Both KE and PE are maximum at y = 0 and minimum at y = A.
