WebGeometric ray tracing is used to describe the propagation of light rays through a lens system or optical instrument, allowing the image-forming properties of the system to be modeled. The following effects can be integrated into a ray tracer in a straightforward fashion: Dispersion leads to chromatic aberration; Polarization. Crystal optics WebBase area = length × breadth = 48 units 2. Base perimeter = 2 (l + b) = 28 units. Height = 4 units. Substituting the values of the base area, base perimeter, and height in the surface area formula we get, Surface area of prism = (2 × 48) + (28 × 4) = 208 units 2. Therefore, the surface area of the prism is 208 units 2.
