A vibrator of frequency 60Hz is used in generating transverse stationary waves in a long thin wire, If the average distance between successive nodes on the wire is 45cm, find the speed of the transverse waves in the wire.
f = 60Hz, l = 45cm = 0.45m
λ = 2l = 2 x 0.45 = 0.90m V = fλ = 0.9 x 60 = 54m/s
