1.	For the wave discribed in Exercise 15.8, plot the displacement (y) versus (t) graphs dor x = 0.2 and 4 cm. What are shapes of these graphs? In which aspects does the oscillatory motion in travelling wave differ from one point to another: amplitude, frequency or phase?
Answer» Solution :All the GRAPHS are SINUSOIDAL. They have same amplitude and FREQUENCY, but DIFFERENT initial phases.
