Wavw velocity is inversely proportional to what? (a) period (b) wavelength (c) amplitude (d) All of these

Answer 1

V = WF. V = Velocity in meters per
second, W = wavelength in meters,
f = frequency in hertz (cycles per sec)
F = 1/P. Therefore, V = W (1/P) = W/P. Therefore V is inversely proportional to the period(P). ans. = a.
