English Word                                                         Definition

Reflection                                                bouncing of a wave off a surface

Concave mirror                                        curves inward, like the bowl of a spoon

Convex mirror                                 curves outward, like the back of a spoon

Focal Point                                               where parallel light rays converge after reflecting from a mirror

Focal Length                                           distance along the optical axis from the mirror to the focal point

Refraction                bending of a wave as it changes speed while moving from one medium to another

Lens             transparent object with at least one curved side that causes light to change direction

Concave lens        is thicker at the edges than in the middle

Convex lens        is thicker in the middle than at the edges

Microscope An instrument that uses light and a system of lenses and mirrors to magnify objects
