Question

a large ripple tanl with a vibrator working at a frequency of 30Hz produces 25 complete waves in a distance of 50cm . find velocity of wave

Answer 1

Answer:

60cm $sec^{-1}$

Explanation:

distance per wave=50cm/25=2cm

frequency=30Hz= 30$sec^{-1}$

velocity=distance/time

V= 2cm×30$sec^{-1}$

=60cm $sec^{-1}$
