CONCEPT MAP
Reflection of Light
-
rays from an object reflect off the mirror into our eyes, but we see them behind the mirror
-
incident ray, reflected ray and normal are always on the same plane
-
-
-
-
Thin Converging Lens
-
-
-
principal axis-line that goes through optical center, and the 2 foci
-
-
Waves
-
-
Diffraction
waves bend round the sides of an obstacle, or spread out as they pass through a gap
Dispersion of Light
when light is refracted by a prism the incidence ray is not parallel to the emergent ray, since the prism's sides are not parallel
white light is a mixture of colors, and the prism refracts by a different amount
red, orange, yellow, green, blue, indigo, violet
-
Refraction of Light
it is the bending when light travels from one medium to another due to the change in speed of the ray of light
