electromagnetic wave
does not need a medium in which to travel
medium
the material in which a wave travels
concave lens
a lens that is thicker at the edges than in the middle
refraction
the bending of a light wave due to a change in speed
law of reflection
the angle of incidence is equal to the angle of reflection
focal length
the distance along the optical axis from the center of a mirror to the focal point
focal point
the point through which all reflected light rays pass
convex lens
a lens that is thicker in the center than at the edges
reflection
at the the process of light striking object and bouncing off
lens
a transparent object with at least one curved side that causes light to bend
300 million m/s

light ray
narrow beam of light traveling in a straight line
microscope
a combination of lenses used to magnify small objects

materials such as waxed paper and frosted glass
camera
uses a convex lens to form an image on a medium
