occurs when a wave strikes an object of surface and bounces off.

bending of a wave as it moves from one medium to another

bending of a wave around an object

matter that a wave passes through

narrow beam of light traveling in a straight line

The ray of light that strikes a surface before reflection

the ray of light that strikes a wave after reflection

states that when a wave is reflected, the angle of incidence is equal to that of refleciton

the characteristic of a material where it cannot be seen through

when a material can be partially seen through

when a material can be completely seen through.

a glass shape that can refract light, splitting the light.

uses two convex lenses to gather light and form an image of a distant object.

uses a concave mirror to gather light from distant objects

a lens that is thicker in the center than at the edges

a mirror where the edges are thicker than the middle

a mirror where the center is thicker than the edges

a mirror that is the same thickness all around with no curve

the point on the axis of a lens or mirror to which parallel rays of light converge or from which they appear to diverge after refraction or reflection

The distance between the center of a lens or curved mirror and its focus.
