convex lens
concave lens
A concave mirror is curved
inward
outward
Store security mirrors and rear view mirrors are both examples of
concave mirrors
convex mirrors
The law of reflection states that when light rays strike a plane mirror they are
reflected at a smaller angle at which they arrived
reflected at the same angle at which they arrived
reflected at a larger angle at which they arrived

Light that has wavelength of 5 x 10-9 m in air has wavelength 4 x 10-9 m in a transparent material. What is the index of refraction of the material? (Remember, f never changes as waves go from one medium into another. Only wavelength and speed do).
