What is reflection
100
the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density
What is refraction
200
contracts and expands the pupil to adjust to light and distance
What is an iris
200

What is a convex lens
200
