Web1. It can be reflected, 2. It can be absorbed. 3.It can be transmitted ( slowed to pass through). Any combination of these three things can happen simultaneously. Light rays that travel parallel to the optical axis and strike the mirror are reflected so they pass through a single point on the optical axis. WebJan 15, 2024 · This allows the design of an optical surface which refracts the emitted rays towards the calculated points R (Figure 2c). In order to find an optical element which is capable to fulfil this condition, the radiant intensity distributions IL(θ) and IS(θ) are discretized into M rays with different propagation angles θ L i and θ S i respectively, with i …

WebEven if the lens' curvature is not circular, it can focus the light rays to a point. It's just an assumption, for the sake of simplicity. We are just learning the basics of ray optics, so we are simplifying things to our convenience. Lenses don't always need to be symmetrical. Eye lens, as you said, isn't symmetrical.

WebSpecifically, we choose two rays: the first ray travels along the optical axis and the second ray travels elsewhere (say, point Q).
