How Do Objects Bend Light?

Prisms As light waves enter, and exit, a prism the light waves change directions. Each color refracts a slightly different amount. This separates the white light into its component colors.

Objects, whether transparent or opaque, appear to be a certain color because of the other colors they absorb.

Rainbows May form anytime water droplets are in the air. The droplets act like tiny prisms. Not all rainy days have rainbows because you have to have sunlight too.

Convex lens Thicker in the middle Objects appear to be LARGER Objects may appear to be upside down

Concave lens Thicker at the edges Objects appear to be smaller Objects always appear upright

Convex or Concave?

Mirrors can be convex and concave too!

Each of your eyes contains a convex lens.

Some people have trouble seeing because of the shape of their eyes.

Corrective lenses, glasses or contacts, help get the focal point back on the retina.
