Refraction
|
lenses work on the idea that light bends when it enters a different material which is refraction
|
|
|
how is the angle of refraction measured
|
the angle of refraction, θr, is measured between the refracted ray and the normal
|
|
|
when will the light bend toward the normal?
|
if the density is higher (such as plastic or glass) the light will bend towards the normal
|
|
|
when will the light bend away from the normal?
|
if the density is lower the light will bend away from the normal
|
|
|
Lense types
|
concave lenses and convex lenses
|
|
|
a convex lens is?
|
it will cause incoming light rays that are parallel to converge
|
|
|
a concave lens is?
|
it will cause incoming light rays that are parallel to diverge
