Science exam 6.2

Extending human vision (eye-like things) say how many and what lenses it uses

Microscope 2 convex lenses to magnify small, close objects
Refracting Telescope 2 convex lenses, lenses with longer focal lengths
Reflecting telescope 1 concave mirror, 1 plane mirror, 1 convex lens
Binoculars 2 refracting telescopes (2 convex lenses), light reflected several times to keep it short
Camera Camera works very much like human eye. Instead of a lens that can change shape to focus the light on the "screen",camera moves position of lens to change distance from lens to screen
