Question

A sonometer wire of length of 50 cm is vibrating in fundamental mode with a frequency of 100hz.Its speed?

Answer 1

Answer:

its speed is 100m/s

its speed is 100m/s while it's waves are transverse waves.

SONOMETER - Basically sonometer is defined "it is an instrument which is used to measure the sensitivity of hearing.

Sonometer is consisting of a wooden rectangular hollow box, and a uniform wire attached to one end while the rest end of wire is passed over the horizontal edges.

A sonometer which contain wire of length of 50cm is vibrating in fundamental mode with a frequency of 100hz.

Answer 2

Hey Dear,

◆ Answer -

v = 100 m/s

◆ Explanation -

Wavelength of the wire is calculated as -

λ = 2l

λ = 2 × 50

λ = 100 cm

λ = 1 m

Speed of the wave is calculated as -

v = f.λ

v = 100 × 1

v = 100 m/s

Therefore, speed of the wave is 100 m/s.

Hope this helped you. Thank for asking..
