Reflection
The definition of refelction
When a ray strikes a surface and bounces off
define refraction
The bending of light when it passes from one medium to another.
Difine Total Internal Reflection
When all the incident light is reflected back into the original medium.
A lens bends parallel light rays inward to meet at a focal point.
In a plane mirror, the image is the same size as what
The object
Light is refracted because it travels at different ______ in different materials.
Speeds
This is the minimum angle of incidence at which total internal reflection occurs.
Critical angle
Define Diverging Lense
A lens that causes parallel rays of light to spread out.
This type of image is formed by a plane mirror and cannot be projected on a screen.
Virtual image
This measures how much light slows down in a material.
Refractive index
Total internal reflection happens when light stays inside this.
Original medium
This is the point where parallel rays meet in a converging lens.
Focal Point
