What are some ways that light can be controlled and what does it do to the light

- - pass the light through a lens

The path of the light is bent (refracted) to a new direction.

- - bounce the light off a shiny surface

The light is sent back (reflected) in the direction from which it arrived.

- - pass the light through a prism

The light is spread out according to the different wavelengths

that may be in it.

- - put something black in the light's path

The light is completely absorbed and is never seen again.

- - turn the light off

The source stops emitting light.

- - throw a towel over the lamp

The light is absorbed in the towel, and not seen outside of it.
