Which one of the following frequency can set the string into resonant vibration?
If a guitar string has a fundamental frequency of 500Hz

a)250Hz
b)750Hz
c)1500Hz
d)1750Hz

It has to be an integral multiple of 500 Hz. Only one of those frequencies meets that requirement.

• Phys sci -

what does that mean?

• Phys sci -

The ratio of a resonant frequency to 500 Hz (the fundamental) must be an integer. That is only true for one of the four choices.

That is what it means.
