tracing the path of light through a prism animation

Tracing the Path of Light Through a Prism - Place a prism on a white sheet of paper with the triangular face on the sheet and trace its boundary ABC. Fix two pins T and S on one side. Place the prism on the boundary ABC. Looking ..

Angle of deviation is the angle through which an incident ray deviates.Repeat this for different values of angle of incidenc..

Sir Isaac Newton, while studying the images of heavenly bodies formed by a lens, found that the images were coloured at the edges. In 1665, to investigate this, he performed an experiment using a prism. Newton darkened his room at Trinity College, Cambridge and allowed a beam of sunlight..

Let us now perform an experiment and find out how light gets refracted when it is incident on a rectangular glass slab. Place a rectangular glass slab on a white sheet of paper fixed on a drawing board. Trace the boundary ABCD of the glass slab. Remove the glass slab. D..

>A ray of light passing through the focus of a concave mirror after reflection emerges parallel to the principal axis. A ray of light passing through the centre of curvature of a concave mirror retraces its path after reflection as the ray passing through the centre of..

Question: Explain how is the principle of echo used by (a) the bat during its flight at night. (b) the dolphin to locate small fish as its prey. Answer: (a) Bats during the flight send a series of twittering sound waves which strike against the object in their path of lig..

Summary - Ray optics is also called geometrical optics as it uses the geometry of straight-line paths (rays) to explain the optical phenomena. Ray optics, infact, is the limiting case of wave optics. This means for most practical purposes, we can ignore the deviation from straight-line ..

. The path along which the impulses travel in a reflex are called the reflex arc. There are five sense organs in humans - eyes, ears, nose, tongue and skin. Eyes are the visual sensory organs. They are equipped with the photoreceptors called the rods and cones. Each eye is a spherical str..
