Bob is talking to Alice using a tin can telephone, which consists of two steel cans connected by a 20-m-long taut steel wire. The wire has a linear density of 7.85 g/m, and the tension on the wire is 29.5 N. The sound waves leave Bob's mouth, are collected by the can on the left, and then create vibrations in the wire, which travel to Alice's can and are transformed back into sound waves in air. Alice hears both the sound waves that have traveled through the wire (wave 1) and those that have traveled through the air (wave 2), bypassing the wire. Which wave arrives sooner and by how much?
