Absorption in terms of light and lens- when a ray of light enters a
lens some of the light will not completely travel
through the lens
Deviation (Angle of) the angle a ray of light is changed from its original
path
Diffuse Relection a reflection from a rough surface- the reflection does
not produce a clear image
Incidence (Angle of) the angle which a ray of light makes the surface of a
refracting medium
Reflection the return of light waves from a surface the
production of an image
Refraction the bending of light when going from one medium
into another
Refraction (Angle of) the angle created when a ray of light passes from
one medium into another
Specular Reflection the forming of a clear image when light strikes a
surface
Why is a red pencil red? It reflects red rays back toward the eye and absorbs
all the other rays of visible light
, Why is the blacktop black? It does not reflect any rays back toward your eye;
rather it absorbs them all
If a light beam passes through a green The green rays are refracted through the lens and all
sunglasses lens, why will the exciting other color rays are absorbed by the pigments in the
light be green? lens material
When a ray of light travels from air into If the ray is perpendicular to the surface it slows
water (which is denser than air) what down but does not change direction; it is not
happens to the ray of light if the ray is deviated or displaced
perpendicular to the surface?
When a ray of light travels from air into If the ray is not perpendicular to the surface it slows
water (which is denser than air) what down and changes direction toward the normal; it is
happens to the ray of light if the ray is deviated from its original path
not perpendicular to the surface?
When a ray of light travels from water If the ray is perpendicular to the surface it speeds up
into air ( which is rarer than water) but does not change direction; it is not deviated or
what happens to the ray of light if the displaced
ray is perpendicular to the surface?

what happens to the ray of light if the normal; it is deviated from its original path
ray of light is not perpendicular to the

What does critical angle mean? a light ray leaving a denser material is rarer material
that is at an angle of normal that results in it traveling
parallel to the surface of the material. If the angle of
incidence is greater than the critical angle the ray will
reflect inside the material and will not exit into the
rarer material
What are the three things that can absorbed, reflected, refracted
happen to a ray of light when it passes
through a lens?
