A sinusoidal travelling wave in a string has a velocity of
propagation 300 m/sec. The time period of oscillations of the particles
of the string is 0.04 sec. The phase difference between the oscillations
of two points at distances 10 m and 16 m respectively from source of
oscillation is nπ. Find n.
