Summary
Light travels in straight lines
formation of shadows and images understood by straight light rays
light travels through vacuum at 299,792,458 m/s
we detect different frequency visible electromagnetic radiation as light with different colors, additive effect of colors, complimentary colors
light reflects from surfaces
the laws of reflection: (1) the angles the incident and reflected rays make with the normal to the surface are equal (2) the reflected ray lies in the same plane as the normal and incident ray
mirrors produce real and virtual images
light converges to from real images which can be projected
light only appears to come from virtual images, which cannot be projected
constructing the image for flat and curved mirrors
