UVa. Today’s Topics. A bit more about mirrors…. Refraction. Lenses. Ray tracing to locate image. Concave Mirror Focusing Sunlight. This solar collector is really many small flat mirrors, but equivalent to a concave mirror focusing parallel rays to a point half way from the center of the mirror to its center of curvature.. 1. Today we will.... Learn how combinations of lenses form images. Thin lens equation & magnification. Learn about the compound microscope. Eyepiece & objective . Total magnification. Learn about limits to resolution. Many of these look . very similar. and may be hard to distinguish between!. We . will break these tools down into smaller sub-groups:.
