A wire of length 400cm is stretched between two fixed points. When plucked, its fundamental frequency is 150Hz. Calculate the speed of the wave produced.

A.

250ms1

B.

625ms1

C.

1200ms1

D.

1500ms1

Correct answer is C

The fundamental frequency (f0) = v2l

f0=150Hz;l=400cm=4m

150=v2×4

v=150×8=1200ms1
