1. The problem statement, all variables and given/known data Alas, after a sybaritic festival, the cheap upright piano in your fraternity house is found upright at the bottom of the house swimming pool. You decide to play Handel's Water music but first test the sound of middle C (261.6 HZ). The speed of sound in water is 1.48x10^3 m/s. What is the wavelength of the sound wave corresponding to middle C in the pool? What is the assumptions are needed to make the determination? v=1.48x10^3 m/s f=261.6 Hz 2. Relevant equations λ=v/f v=(β/ρ)^1/2 3. The attempt at a solution I just plugged it into the equation λ=v/f and got 5.66 m. Which I think is correct but im not sure if I know all the assumptions or not. Thats where the next equation comes in, v=(β/ρ)^1/2, because I assume that to get the speed of sound in the water.
