Answer 1

Answer:

For a standing wave to be produced on a string such that one end is tied and the other is free

The length of the vibrating string must be an odd multiple of lambda / 4.

Where lambda is the wavelength of the associated wave.

Also, if the string is tied at both the ends, then the length of the vibrating string must be an integer multiple of lambda or the same as saying an even multiple of lambda / 2
