If a standing wave is vibrating in the fourth harmonic and the wavelength is λ, what is the length of the string.
If a standing wave is vibrating in the fourth harmonic and the wavelength is λ, what is the length of the string. Correct Answer 2λ
If the length of string is L, then the wavelength of the standing wave is 2L/n. Or we can say L = nλ/2, where n corresponds to nth harmonic. ∴ L = 4λ/2 = 2λ.
