Physics Question on Waves

A stretched string of length ll fixed at both ends can sustain stationary waves of wavelength λ\lambda such that (nn is an integer)

A

λ=n22l\lambda = \frac{n^2}{2l}

B

λ=l22n\lambda = \frac{l^2}{2n}

C

λ=2nl\lambda = 2nl

D

λ=2ln\lambda = \frac{2l}{n}

Answer

λ=2ln\lambda = \frac{2l}{n}

Explanation

Solution

Answer (d) λ=2ln\lambda = \frac{2l}{n}
