Two copper wires of radii 'r_1' and 'r_2' (r_1 > r_2) are subjected to same tension and are plucked. The transverse waves will

MHT CET 2022 Physics question

Two copper wires of radii 'r' and 'r' (r > r) are subjected to same tension and are plucked. The transverse waves will

(A)not travel through both the wires
(B)travel with the same velocity in both the wires
(C)travel faster in the thinner wireCorrect
(D)travel faster in the thicker wire

Answer: (C)

Solution

The speed of a transverse wave on a stretched string is , where is the mass per unit length, for a wire of density . Both wires are copper (same ) and have the same tension , so \propto$
