How to represent light as a sinusoidal function

AI Thread Summary
Light can be represented as a sinusoidal function on a Cartesian plane, although this simplification overlooks its complexity. The discussion seeks to graph light waves as a two-dimensional sine curve, questioning the feasibility of such representation. Amplitude units for light waves can be expressed in volts per meter (V/m) for electric fields and tesla (T) for magnetic fields. The conversation emphasizes the need for a clear explanation of the equations involved in this representation. Visual resources provided help in understanding electromagnetic waves conceptually.

I have seen many equations light as a wave but none of which have represented light as a simple sinusoidal function. I want to be able to graph light waves on a cartesian plane as one sine curve. I know that light isn't that simple but could light be represented as a 2 dimensional sine curve. Also what would feasible units for amplitude be? Is there a way to represent amplitude both in v/m and tesla for electric and magnetic fields? If you could explain each part of the equation that would be great.

You are probably looking for something more quantitative but this site helped me get some sort of visual understating of E&M waves.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
