P and Q are fixed points at the end of a string. A transverse stationary wave of constant maximum amplitude is formed on the string. [Figure 27.1] P, R and Q are the only points on the string where nodes are formed. S and T are two points on the string at a distance x from R. What is the relationship between points S and T?
Athe same amplitude and in phase
Bdifferent amplitudes and in phase
Cthe same amplitude and a phase difference of 180°
Ddifferent amplitudes and a phase difference of 180°
