It is clear that at normal incidence (i=0 degrees) 98% of the light is transmitted into the water, while at grazing incidence (i=90 degrees) both polarization components are almost completely reflected. In the figure shown below the reflectance for each direction of polarization has been plotted as a function of the angle of incidence. This is the plane containing the incident ray, reflected ray, refracted ray, and the normal to the surface at the point where the incident ray strikes it. The application of Maxwell's equations of electrodynamics to this situation leads to rather simple expressions for the reflectances of waves with polarizations either perpendicular to or parallel to the plane of incidence. The dependence on the light frequency (dispersion) is comparatively weak. the reflectance, depends strongly on the angle of incidence 'i' (see the figure) and the wave's polarization. The fraction of the incident intensity (which is energy per unit area per unit time) that is reflected, i.e. When a wave of visible light travelling through air strikes a water surface its incident energy is partially reflected from the surface and partially transmitted into the water. Each of these oscillations is referred to as plane polarized, with the plane of polarization being the one containing both the line of oscillation and the direction of propagation. This can always be thought of as the superposition of two independent oscillations, with the same frequency, along mutually perpendicular lines with fixed orientations in space. In the most general case the electric field vector periodically changes direction and magnitude as it rotates around an ellipse, i.e. Light is a transverse electromagnetic wave, meaning that it consists of mutually perpendicular oscillatory electric and magnetic fields which are both perpendicular to the direction of propagation. I guess I will just have to wait and see.External Reflection from a Water Surface External Reflection from a Water Surface We aren't even close to knowing all the things we need to know about the conic sections. I am really curious to see if the equations are harder to solve then the 2d equations. Which I figured out while doing this project because I learned there was a 3d case to all of these, which it blew my mind.
I feel like we learned a lot of stuff this unit, but I bet that was just the basic and there is much more to come. Then, there is the circle, which is unique, its center point is both of the foci. A good example of this would be a cd because it clearly shows the center point. Last but not least, there is the hyberbola, which is a smoke stack structure that sends the rays outward instead of inward. For example, the stars in the sky when you stand in one place and see something but someone standing 20 miles away cannot see it. For the ellipse though it is about the same properties except it is from one focus to the other focus instead of wall to focus. I think it is pretty cool how in in a parabola, if the ray approaches the curved line it will reflect to the focus from any point or angle inside of the parabola's "mouth." For example, a satelite, how it sends and receives signals. Throughout this unit, I learned a lot about the conic sections.
