It is typically characterized by their angle of minimum deviation and this minimum deviation is achieved by adjusting the incident angle until the ray passes through the prism parallel to the bottom of the prism.
In case of the optical aspect the application causes light of different colors to be refracted differently and to leave the prisms at different angles, creating an effect similar to a rainbow. This can be used to separate a beam of white light into its constituent spectrum of colors.
As you become more knowledgeable in the visual arts, you become more capable of seeing the various aspects of an image. Your approach will be more discerning when it comes to the elements of composition, the character of the color, the placement of the focused plane and depth of field, the level of detail, sharpness, and other characteristics of the image.
Lenses are designed to a standard, with a set of design parameters that include several capabilities that the designer has determined are significant to the intend and a level of performance in these areas that is capable. Generally, the high-end lenses have a more linear performance across a wider variety of apertures than the lower-end lenses.
The other obvious and most wide field is in case somehow your vision is blurred then you have take the aid of such optical tool for convenience. This small tool has other wider application with respect to to various electronic appliances.
A wave plate works by shifting the phase between two vertical polarization
components of the light wave. A typical plate is simply a birefringent crystal with a carefully selected orientation and thickness. The crystal is cut so that the extraordinary axis or "optic axis" is parallel to the surfaces of the plate.
Light polarized along this axis travels through the crystal at a dissimilar speed than light with the vertical polarization, creating a phase difference.
When the unusual index is smaller than the ordinary index, as in calcite, the unusual axis is called the "fast axis" and the perpendicular direction in the plane of the surfaces is called the "slow axis".
