What is Encaustic Paint. Encaustic is a wax based paint (composed of beeswax, resin and pigment), which is kept molten on a heated palette. It is applied to an absorbent surface and then reheated in order to fuse the paint. The word âencausticâ comes from the Greek word enkaiein, meaning to burn in, referring to the process of fusing the paint.
1 Linear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180Â°. For example, carbon dioxide and nitric oxide have a linear molecular shape.  Trigonal planar: Molecules with the trigonal planar shape are somewhat triangular and in one plane (flat).
The amount of bending that a light ray experiences can be expressed in terms of the angle of refraction (more accurately, by the difference between the angle of refraction and the angle of incidence). A ray of light may approach the boundary at an angle of incidence of 45-degrees and bend towards the normal. If the medium into which it enters causes a small amount of refraction, then the angle of refraction might be a value of about 42-degrees. On the other hand if the medium into which the light enters causes a large amount of refraction, the angle of refraction might be 22-degrees.
