Questions
A travelling wave passes a point of observation. At this point, the time interval between successive crests is 0.2 seconds then
a
The wavelength is 5 m
b
The frequency is 5 Hz
c
The velocity of propagation is 5 m/s
d
The wavelength is 0.2 m
detailed solution
Correct option is B
Phase difference between two successive crest is 2π. Also, phase difference (Δφ)=2πT time interval (Δt)⇒2π=2πT×0.2⇒1T=5sec−1⇒n=5 HzTalk to our academic expert!
