1. Suppose a wave is traveling from one medium to another. What characteristic of the wave would you expect to be the same in the new medium? Defend your answer. 2. In Lab 5-Waves 1, found that the material properties of a string that determine the speed of a wave along that string are the tension in the string T and the linear mass density H . The equation we developed can be extended to describe the speed of a wave in any medium as: 'v = Force factor Inertial factor in other words, the wave speed can in general be found to depend the square root of some elastic property divided by some inertial property. Use this relationship to guide your thinking about the following question: Which of the following choices explains why sound travels faster in water than in air? A. The density of water is greater than the density of air. B. There is much stronger interaction between liquid water molecules than between air molecules. C. Water molecules are heavier than air molecules. D. The wavelength is shorter in water than in air. E. The frequency is higher in water than in air. Defend your
