Ok, so I have many questions about light. My basic understanding can be seen here: http://answers.yahoo.com/question/index?qid=20140117062517AAeH0Dh My first question is, consider transverse waves in water. As the wave moves out, the water molecules move up and down forming the crests and troughs. Considering light, as light moves out, if my understanding in the link above is correct, then the FIELDS are oscillating, i.e. changing in magnitude(in place of the water molecules), and along the line that the light moves(not actually up and down in space,like the water molecules). The frequency is the number of times the strength of the field goes from maximum to minimum and back to maximum in a second, and the wavelength is the distance the light travels when one such cycle is completed. If what I have said above is right, how can this be translated to wavelengths of material particles(say like a photon). It is not possible for the material particle to oscillate at a point, right?
