REFRACTION
WHAT IS REFRACTION OF LIGHT?
WHEN DOES IT HAPPEN?
HOW AND WHEN WILL LIGHT BEND?
WHAT IS REFRACTIVE INDEX?
EFFECTS OF REFRACTION
Refraction of light refers to the change in the
direction of light.
Refraction of light occurs when it passes from
one transparent material into another.
3a.When light moves from glass to air (a less dense
material), it speeds up and is refracted away from
the normal.
Light twists outward when entering
Medium of lower index of refraction
3b. When light moves from air to glass (a denser material),
it slows down and is refracted towards the normal.
Light twists inward when entering
medium of higher index of refraction
4. The effects of refraction are causing an object to appear nearer than it actually is when a transparent material is on top.
