Properties of Light
thin converging lens

-
-
-
magnifying glass: when convex lens used like this - object closer to convex than principal focus, rays never converge. They appear from behind lens. Image is upright, magnified and virtual
reflection of light
plane mirrors produce reflection, ray from object reflect off mirror to our eyes but we see them behind mirror
same size, same distance from mirror, line joining mirror and object meet at right angle, image is virtual
laws of reflection
-
incident ray, reflected ray and normal are always on same plane
-
-
-
refraction of light
refraction: the bending when light travels from one medium to another due to change in speed of ray of light
-
-
application: communications, medicine(endoscope)
dispersion of light
when light is refracted by prism, incidence ray is not parallel to emergent ray since prism's sides are not parallel
-
white light(mixture of colors), prism refract each color(red-deviated least, violet deviated most)
