Question on: JAMB Physics - 1998
A steel wire of length 0.50m is stretched between two fixed points and its fundamental frequency is 200Hz. The speed of the wave in the wire is
A
100ms-1
B
120ms-1
C
200ms-1
D
250ms-1
Ask EduPadi AI for a detailed answer
Correct Option: C
In strings, \(\lambda\) = 2L
V = F\(\lambda\)
= 200 x 2 x 0.5
= 200ms-1
V = F\(\lambda\)
= 200 x 2 x 0.5
= 200ms-1
