Analyze: Click Reset. Set the Frequency to 0.80 Hz, Tension to 2.0 N, and Density to 2.0 kg/m. Click Play, and then click Pause. Turn on Show rulers.
Answer the following:
What is the wavelength?
What is the wave speed?
How are the wavelength, frequency, and wave speed related? In general, the wave speed (v) can be calculated from the frequency (f) and wavelength (λ) using the formula v = f • λ.
What is the wavelength of a wave with f = 0.9 Hz and v = 154.9 cm/s? To check, set Frequency to 0.90 Hz, Tension to 2.4 N, and Density to 1.0 kg/m.
