Optics Unit 2
Lens and refractions
Concave lens= diverge( can only be virtual images+ the lines refracts back toward the focal point on the same side
-
-
When all of the light beams meet create a real image when they don't meet you have to extend the lines and create a virtual image
-
Focal points = the point at which rays meet after reflection or refraction(The distance between the focal points is always the same)

Optical Illusions
When you look at a color for 30 second then at a blank white piece of paper it's the opposite color on the color wheel
-
-
When all of the colors of a wheel spin very fast they blend into 1 color because the rods don't have enough time to differentiate the sectors
When you look at a black image then a white piece of paper you only see the outline because the cones are overworked
