DNotes from class:- There is more spreading as focal length increases- To fix spherical aberration you need to make a parabolic surface- If you were to put a light at the focal point, the light will reflect off the mirror and go out parallel from that- Planoconvex plane on one side and convex on other, still converging- In order to have more dispersion you need to increase the index of refraction- Same index of refraction of the material you’re in and that means your invisible- Fresnel lens concentric grooves, overhead projectors, light houses –important becaue they are a lighter type of lens- If the object is between the focal point and the center of curvature of a concave spherical mirror, then the image is on the same side of the mirror, real image, and is larger- If the object is on the center of curvature of a concave spherical mirror, then the image is a real image, same size, and inverted- From: 1/f = 1/p +1/q know: that if f is constant, then p and q will change inversely- Convex lens and the light
