A wave pulse is generated in a string that lies along an x-axis. At the points A and B, as shown in figure, if RA and RB are ratio of wave speed to the particle speed respectively then :

A
RA>RB
B
RB>RA
C
RA = RB
D
Information is insufficient to decide.
Answer
RA>RB
Explanation
Solution
Slope at any point on y-x curve in wave motion represents ratio of particle speed to wave speed. slope B > slope A hence RA > RB.
