A2 cm string that is fastened at both sides is plucked. what is the wavelength of the n = 3 standing wave?

To determined the value of wavelength of the standing wave, we use the formula

Here, is the wavelength, L is the string length and n is integer.

Given,   n = 3 and  L = 2 cm.

Substituting these values in above formula, we get

Thus, the wavelength of the standing wave is 1.33 cm.
