Question

In lab S1, you lightly pinched the wire and moved your fingers until you found a resonance length. Suppose that you were inadvertently increasing the tension when you found and measured the resonance length. How would this affect the comparison between the theoretical wavelength and your experimentally-determined wavelength?

a) Increasing the tension would have no effect on the wavelength.

b) Increasing the tension would cause the experimental wavelength to be larger than the theoretical wavelength. (i.e. Your theoretical wavelength would be too small.)     I

c) ncreasing the tension would cause the experimental wavelength to be smaller than the theoretical wavelength. (i.e. Your theoretical wavelength would be too large.)

Explanation / Answer

According to laws of trasvers waves condition 1 frequeny is inversely proportional to length (or) wavelength

and also condition 2 frequency is directly proportional to square root of tension

basing on both condition square root of tension is inversely proportional wavelength so tension increasing wavelength decresing so option B is correct
