Reflection of light occurs
when light bends to go around an obstacle and cast a shadow
when light disappears into a medium
when light bends when it encounters a new medium and bends
when light strikes a barrier and bounces back
Refraction of light occurs
when light bends to go around an obstacle and cast a shadow
when light bends when it encounters a new medium
when light disappears into a new medium
when light strikes a barrier and bounces back
Diffraction of light occurs
when light bends to go around an obstacle and makes a shadow look fuzzy
when light disappears into a medium
when light strikes a barrier and bounces back
when light encounters a new medium and bends
Absorption of light occurs when
Light bends to go around an obstacle and makes shadows look fuzzy
Disappears into a medium and changes to heat
light strikes a barrier and bounces back
light bends when it enters a new medium.
