Does the law of reflection hold for curved mirrors? |
[Improve]
Yes. The angle of reflection = the angle of incidence. This is where pictures of ray traces (see the link below) come in very handy, keeping in mind that a ray trace is a very small (the magical physics *very small*) portion of the light that is falling on the mirror at a very small period of time. It works easiest for curved mirrors if the mirror has the reflective surface on the front (where the light is coming from) so we don't have to play with the refractive equations of the intermediate media. The mathematics of the angle of incidence and reflection is fairly easy for linear equation surfaces, like shperical, parabolic and hyperbolic, but gets a little more involved for nonlinear surfaces (like wrinkled tin foil).
