A first-harmonic standing wave is formed on a vertical string of length 3.0 m using a vibration generator. The boundary conditions for this string are that it is fixed at one boundary and free at the other boundary.

                                          M18/4/PHYSI/SPM/ENG/TZ1/13

The generator vibrates at a frequency of 300 Hz.

What is the speed of the wave on the string?

A.     0.90 km s–1

B.     1.2 km s–1

C.     1.8 km s–1

D.     3.6 km s–1
