Objective: Find $\lambda$ of the standing wave generated on this string
Now if a wave is generated here we have two nodes at the fixed (clamped) ends and again we have a node at the joint b/w A and B. So at first I tried to find out the $\lambda$ (wavelength) for the wave, but I am facing a major problem.
The distance b/w the three consecutive nodes are not the same. So can such a wave be generated? please help me.
