Objective: To determine the speed of a wave. Equipment: Simulation Theory: For any wave (electromagnetic or physical wave: For wave on string: v = v = speed of wave (m/s) f = frequency of oscillation (hz) ʎ = wave length (m) v = f μ f = tension of the string (N) µ = linear mass density (mass/length) ʎ π v = f = v∙ 1 λ y-axis x-axis slope = v
Procedure: The simulation was set to a specified frequency and the wavelength was measured. This was repeated for each frequency. The velocity was then calculated from the measured wavelengths. Graph: Data: f (Hz) λ 1 (m) λ 2 (m) λ (m) 1/ λ m -1 v = f λ (m.s) 1.50 0.043 0.044 0.043 5 22.99 0.065 2 1.75 0.036 0.035 0.035 5 28.16 7 0.062 1 2.00 0.031 0.032 0.031 5 31.75 0.063 0 2.25 0.028 0.029 0.028 5 35.09 0.064 1 2.50 0.023 0.025 0.024 41.67 0.060 0 2.75 0.023 0.023 0.023 43.48 0.063 4 3.00 0.022 0.021 0.021 5 46.51 0.064 5 Average v 0.063 2 Calculations: From graph: 20 25 30 35 40 45 50 0.00 0.50 1.00 1.50 2.00 2.50 3.00 3.50 1.50 1.75 2.00 2.25 2.50 2.75 3.00 f(x) = 0.06 x + 0.04 Lab 9: Waves 1/λ (m) f (hz)
