curved surface that bends light by refraction
lens
diverging lens
convex
converging lens
concave
point which all incident rays pass through
focal point
light strikes a surface and comes back at a different angle
reflection
bending of light rays
refraction
path of a light ray
optical axis
light striking a non-shiny surface
diffuse reflection
a dispersive object
prism
distance between object and ooptical element
object distance
a lens to see outerspace
telescope
a mirror or shiny surface creates this
specular reflection
window glass
transparent
frosted glass
translucent
painted glass
opaque
angle between incident ray and normal
angle of incidence
angle between reflected light and normal
angle of reflection
the angle of incidence equals the angle of reflection
law of reflection
an illusion created by light
