A) 2500 s
B) 75 s
C) 4 s
D) 0.25 s
Correct Answer: C
Solution :
The distance between the two consecutive crests in transverse wave motion is called wavelength. The boat bounces up, i.e., it travels from crest to the consecutive crest along wave motion. Wavelength = distance between two consecutive crests That is, \[\lambda =100\,\,m\] \[\operatorname{Velocity} of wave = 25 m/s\] Hence, time in one bounce of boat \[t=\frac{\lambda }{\nu }=\frac{100}{25}=4\,s\]
