WebA ray diagram to show how a convex lens can focus light. Convex lenses are found in: magnifying glasses; spectacles for people with long-sight (who can see distant objects clearly but not nearby ones) WebA prism having an angle of 90 between its two refracting surface and the other two angles each equal to 45 ∘ ,is called a total reflecting prism because the incident light normally on any of its faces,suffer total internal reflection inside the prism. Due to this behavior, a total reflecting prism is used for the following three purposes.

WebPeriscope is a tube in each end of which there are plane mirrors set parallel to each other at 45 degree angle. The image formed by plane mirror is virtual and laterally inverted. When a ray reflected by 1st mirror becomes incident ray for 2nd one, this laterally inverted incident ray gets reflected by 2nd mirror and results in a virtual image ... WebA periscope is defined as an instrument used for observing over, around or through an obstacle or object which is prevented by direct line of sight. It consists of an outer case with mirrors at each end at 45° angle. These mirrors are placed parallel to the surface.
