Question

In 3.0 seconds, a wave generator produces 15 pulses that spread over a distance of 45 centimeters. Calculate the wave's frequency.

Answer 1

0.2 Hz = v / (0.03 m)
6.67 m/s
best i can guess

Answer 2

5.0 Hz

Step-by-step explanation:

period= time/number of pulses

=.2

f=1/period because they're inverses

1/.2= 5.0 Hz

OR

frequency=distance/number of pulses
