Question

A person vibrates the end of a string sending transverse waves down the string. If the person then doubles the rate at which he vibrates the string while maintaining the same tension, the speed of the waves1- doubles while the wavelength doubled.2- is unchanged while the wavelength is halved.3- doubles while the wavelength is halved.4- is unchanged while the wavelength is doubled.

Answer 1

Given

A person vibrates the end of a string sending transverse waves down the string. If the person then doubles the rate at which he vibrates the string while maintaining the same tension

To find

The speed of the waves

Step-by-step explanation

Since there is no change in medium so the speed remains unchanged.

Since the rate of vibration is doubled so teh wavelength becomes halves

Conclusion

The correct option is

2- is unchanged while the wavelength is halved.
