1. Waves transport which of the following from one region to another as they propagate a medium. A.Matter B.Energy C.Both A and B D.Neither A nor B

2. A wire is stretched taught, with tension T, between two posts. The wire is grabbed in the middle, raised a distance d and released, creating a wave with speed v. The speed of the resulting wave, if the wire is raised a distance is 2d before being released, is A.v/4 B.v/2 C.v D.2v E.4v F.Not enough information

3. A wire is stretched taught, with tension T, between two posts. The wire is grabbed in the middle, raised a distance d and released, creating a wave with speed v. If the tension is increased to 4T, the speed of the resulting wave is A.v/4 B.v/2 C.v D.2v E.4v F.Not enough information

4. A wire is stretched taught, with tension T, between two posts. The wire is grabbed in the middle, raised a distance d and released, creating a wave with speed v. The next time, the wire is plucked harder, in an attempt to `impart’ twice as much energy into the wave. The speed of the wave in this instance is A.v/4 B.v/2 C.v D.2v E.4v F.Not enough information

5. A wire is stretched taught, with tension T, between two posts. The wire is grabbed in the middle, raised a distance d and released, creating a wave with speed v. A wire with 4 times the mass of the exact same length is stretched taught with tension T between the same two posts. What is the velocity of a wave through this second wire in terms of v? A.v/4 B.v/2 C.v D.2v E.4v F.Not enough information

6. A wire is stretched taught, with tension T, between two posts. The wire is grabbed in the middle, raised a distance d and released, creating a wave with speed v. A wire, made of the same material and of the same length, but with 4 times the mass is stretched taught with tension T between the same two posts. How can the velocity of the wave for the new wire be made to equal v? A.Scale tension by 4x B.Scale tension by 1/4x C.Its impossible!

7. A steel wire with mass per unit length μ = 0.015 kg/m propagates a wave at speed 340 m/s. Calculate the tension in the wire. RankResponses 1 2 3 4 5 6
