=Unit 10 - Electromagnetic Waves, Light and Light Properties=

Electromagnetic spectrum Doppler effect for light E=hf

1) Parallel Ray - Parallel to optic axis, and then bend towards the focal point on image side. 2) Focal Ray - Will go through the focal point on object's side, and then bend parallel to the optic axis. 3) Central (CHIEF) Ray - Will go through the center of the lens without bending.
 * TYPES OF RAYS:**

1) Real Images - Light rays converge. 2) Virtual Images - Light rays do not come together.
 * TYPES OF IMAGES:**

and be (either) ...

X) Upright - The image appears on the same side of the optic axis. Y) Inverted - The image appears on the opposite side of the optic axis.

AND be (either) ...

b) Enlarged - The image appears larger than the object. d) Reduced - The image appears smaller than the object.
