Two Cu wires of radii

{\mathrm{R}_1}\,\,\mathrm{and}\,\,{\mathrm{R}_2}

such that

\left( {{R_1} > {R_2}} \right)

. Then which of the following is true?

View answer and explanation

Correct option: B

Transverse wave travels faster in thinner wire

Option B (Transverse wave travels faster in thinner wire) is correct because the speed of a transverse wave on a string is inversely proportional to the square root of the linear mass density, which is higher for thicker wires.
