a long spring is used to demonstrate a transverse wave.
wHICh of the following methods can increase the wave speed?
(1)flick the spring harder
(2)increase the speed of vibration
(3)stretch the spring more
d.(2) and (3) only

The wave speed of transverse wave in a long stretched spring is given by:
v = √(T/μ)
T = Tension in the spring
μ = Mass per unit length of the spring
So only (3) can increase the wave speed.Source(s): Myself
