Find the period of a wave given that it has a speed of 200m/s and a wavelength of 2m
The equation for finding the period of the wave is the reciprocal of the frequency
hence th eperiod T =1/f
substitute this into the wave speed equation
v=f x lambda
solve for f
f = v/ lambda
f= 200/ 2
f= 100 Hz
therefore the period = 1/ 100
T = 0.01 seconds
