Debroglie Wavelength

Suggested by De Broglie in about 1913, the path to the wavelength expression for a particle is by analogy to the momentum of a photon. The momentum-wavelength relationship for a photon can be derived ...

Visible Light Waves

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each colour has a different wavelength. Red has the longest wavelength and violet ...
