PhysicsWavesMHT CET

Two wires of same material of radius 'r' and '2r' respectively are welded together end to end. The combination is then used as a sonometer wire under tension 'T'. The joint is kept midway between the two bridges. The ratio of the number of loops formed in the wires such that the joint is a node is [MHT-CET 2021]

Answer: (B)

Solution

Linear density , so the wire of radius 2r has four times larger and wave speed half; for equal half-lengths and the same
