A harmonic transverse wave traveling on a cord has a wavelength of 0.1m, a frequency of 400 Hz, and an amplitude of 0.02m. What is the speed of the wave?

Wavelength (λ) = 0.1m
Frequency (f) = 400Hz = 400/sec
Amplitude (A) = 0.02m
Speed (v) = ?
We know that:-
Frequency (f) = speed (v) / wavelength (λ)
= speed (v) = frequency (f) x wavelength (λ)
= 400/sec x 0.1m
∴ speed (v) = 40m/sec.Source(s): http://myrank.co.in/

v = f L = 400/s * 0.1 m = 40 m/s
