Take out the Slinky Lab from yesterday. We will go over some of the questions. DUE FRIDAY!
Open your notebooks: wave calculations

2. Wave Calculations

3. To find wave speed… S (Wave speed) = λ(wavelength) x f (frequency)
Example: How fast is a wave traveling that has a wavelength of 5m and a frequency of 20 Hz?
100 m/s

4. To find wavelength… λ (Wavelength) = S (wave speed) / f (frequency)
Ex: A wave on a certain banjo string travels at a speed of 200 m/s. Calculate the wavelength a note sounding at a frequency of 440 Hz.
0.45 m

5. To find frequency… f (Frequency) = S (wave speed) / λ (wavelength)
Example: If a wave has a wavelength of 6.2 meters and is travelling at 610 m/s, what is its frequency?
98.4 Hz
