Energy, Wavelength,and Frequency Calculations

All waves have wavelength, amplitude and frequency. If a wave has a short wavelength and a high amplitude it has high energy, but if a wave has a long wavelength and a low amplitude it has low energy. To find the speed of a wave you multiply wavelength and frequency together. Electromagnetic radiation moves through a vacuum at a speed of 3.00*10^8 m/s, so that is what we use for speed of a wave. You can also find how much energy is in a photon with a certain frequency. To do this you multiply the frequency by Planck's constant which is 6.63*10^-34 J*s.

 

This link gives you practice problems on how to find energy, wavelength and frequency, and it shows you how to do it if you get stuck.
