Two wires 1 and 2 same length and same density of radii r and 2r are welded together end to end. The combination is used on sonometer wire and is kept under tension T. The welded point is midway between the two bridges. What would be the ratio of number of loops formed in the wires such that joint is a node when stationary vibrations are set up in the wire ?
Answer:
2
Solution:
Same density, radii r and 2r: ; same tension T and same frequency f.
, so .
Joint is a node and each wire has an integer number of loops: .
