Question

A 10.0 m wire is hung from a high ceiling and held tightly below

Answer 1

Answer:

5 m

Explanation:

Speed of waves is as the product of frequency and wavelength hence expressed as s=fw where f is the frequency of waves in Hz, s is the speed in m/s and w is wavelength in meters.

Making w the subject of the formula then

$w=\frac {s}{f}$

Substituting 335 m/s for s and 67 Hz for f then the wavelength is

$w=\frac {335}{67}=5m$

Wavelength is the distance between successive crests. Since the string is 10m, wavelengths of 5m each will be 2 and the crests will be 3.

Wavelenth=5 m
