Keep in mind this definition is valid for the medium where you measure the wave’s speed and frequency. If the wave propagates slower inside another medium, its resulting wavelength will be shorter. Longitudinal waves form when the particles of the medium vibrate back and forth in the same direction of the traveling wave. The wave can be visualized as compressions and expansions travelling along the medium. The distance between adjacent compressions is the wavelength. Figure 2: Parts of a longitudinal wave. The equation used to find the energy in a mole of photons is E= hc/lambda where h is Planck’s constant, c is the speed of light and is the wavelength of light. The value of E will come out in units that are useful for us to work with if we put the constants and wavelength in the proper units.Possible Answers: Correct answer: Speed is frequency times wavelength. So the frequency must be speed divided by wavelength. In this case: This makes sense as in one second, the wave will have travelled 15m. Each meter is 5 cycles, so over the distance the wave has travelled in one second, it has completed cycles.
