AP EAMCET · PHYSICS · Waves and Sound
The ratio of radii of two wires is \(1: 2\) and the density of their materials are in the ratio \(1: 4\). If same tension is applied to both the wires then the ratio of the speed of transverse waves produced in them is
- A \(1: 16\)
- B \(16: 1\)
- C \(1: 4\)
- D \(4: 1\)
Answer & Solution
