What is the boundary between two materials relating to light called?
Interface
When light travels in straight lines can it be reflected or refracted?
Light always travels in straight lines. When it encounters a boundary between different indices of refraction, the straight line may change to a different direction.
What is the difference between reflected rays of light and refracted rays?
When a beam of light hits a mirror and bounces off, it is reflected. When light is refracted it means the light penetrates into a substance and changes the direction of its movement.
When is light refracted?
light is refracted when it travels through air and then through glass
What are the conditions for total internal reflection to occur?
It occurs when light traveling from one medium to another is completely reflected at the boundary between the two materials. The angle of incidence must be over a certain value (depending on the optical properties of the materials at the boundary).

What happens to light when it strikes the boundary of the two media an angle equal to the critical angle?
It gets refracted so that its direction of propagation is the boundary line.

What happens as light moves from one transparent material into a different transparent material?
IF the refractive indexes of the two materials are not the same number, and IF the light is not traveling perpendicular to the boundary between them, then the direction of the light will change at the boundary. This happens because of the slight difference in the speed of light in the two materials. The process is called "refraction" of light. Without it, eyes and other lenses would not work.
What happened to light when it is refracted?
When light is Refracted it bends when it travels from one medium to another
What happen when light is directed at a transparent materials?
When light is directed at transparent materials, it bounces off of the particles and is refracted accordingly. This causes the light to bend according to the materials refraction index. The higher the refraction index of the material, and the thicker it is, the more it bends the light and separates the colors.
What is refracted light?
The refraction of light is the change in direction of a light ray when it crosses a boundary between two transparent substances. Refraction of light is the change in direction of a light ray due to a change in its speed as it goes from one medium to another.The speed and wavelength of a light ray change when this occurs, but the frequency remains the same.When light travels from denser medium to rarer medium it moves away from the normal [line at right angles to the boundary] and when light travels from rarer to denser it moves towards the normal.
How light is reflected and refracted in a diamond?
Light is reflected and refracted in a diamond based on the angles of its facets relative to the source of the light.
What two factors affect how much light is refracted?
The speed of light . ( but it's mostly ignored , since speed of light is constant in air " 3.0×108" )The Refractive Index of the medium the light is getting into .The angle of incidence to the boundary of the Medium.
