Determine the speed of the wave.
...Determine the speed of the wave.
64 cm/s
32 cm/s
24 cm/s
72 cm/s
Correct answer is D
Speed = Wavelength x Frequency
or
V = fλ, where frequency = 1/period, f = 1/T.
The period was given as 0.125sec and wavelength = 9cm
: f = 1/T = 1/0125 = 8.
V = fλ = 8 × 9 = 72m/s
