Optics
|
The study of how light behaves.
|
|
|
Image
|
Produced by a lens or mirror.
|
|
|
Object
|
What you are actually looking at.
|
|
|
Concave
|
A lens or mirror that is bigger at the ends.
|
|
|
Convex
|
A lens or mirror that is bigger in the middle.
|
|
|
Convergent
|
Light rays that come together.
|
|
|
Divergent
|
Light rays that spread apart.
|
|
|
Normal
|
A line drawn perpendicular to the surface of a mirror or lens.
|
|
|
Mirror
|
An optical device that works by reflection.
|
|
|
Angle of Incidence
|
From the normal to the incoming ray.
|
|
|
Angle of Reflection
|
From the normal to the outgoing ray.
|
|
|
Lens
|
An optical device uses refraction to bend light.
|
|
|
Focus
|
Where all parallel rays converge.
|
|
|
Magnification
|
tells you if the image is larger or smaller, and real or virtual
|
|
|
Total Internal Reflection
|
at the critical angle the light refracts at 90 degrees, parallel to the surface, and past the critical angle the light reflects back into slower medium.
|
|
|
p
|
Distance from the lens or mirror to the object
|
|
|
q
|
Distance from the lens or mirror to the image
|
|
|
h
|
the height of the object
|
|
|
h'
|
the height of the image
|
|
|
M
|
magnification of the lens
|
|
|
can interfere destructively
|
Prove the light is a WAVE
|
|
|
goes through a vacuum
|
Prove the light is a PARTICLE
|
|
|
Electromagnetic Spectrum
|
All light, both visible and invisible.
