Reflection
Virtual
Laterally inverted
Same distance from the mirror to the image and the mirror to the object and same size
Refraction definition?
The bending of light when it passes from one medium to another.
Definition
When all the incident light is reflected back into the original medium.
Name of the two type of lenses
Coverging and diverging
What is reflection?
The change of direction of a
ray when it strikes a surface
without passing through it.
How it is called the measure of how much the light
slows, or how much it is bent?
Refraction index
What is a critical angle.
the minimum angle of incidence at which TIR occurs
Coverging definition
Designed to bend parallel light rays inward to intersect at a specific point.
If the angle of incidence measures 50 how many does the reflection angle measures?
50 or the same
What is the refractive index of diamond.
2.42 approx
Difrence between TIR and critical angle?
The critical angle is the minimum angle at which the refracted ray is 90°, while total internal reflection occurs when the angle of incidence is greater than this angle and all the light is reflected back into the medium.
Diverging lenses
Type of lens that causes parallel rays of light to spread out or diverging
