Question

Define thin prism and give its range of refracting angle.

Answer 1

a prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. ... A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow).

Answer 2

SPECIAL CASE FOR A PRISM WHICH IS VERY THIN. A THIN PRISM IS A PRISM HAVING ANGLE OF PRISM IS VERY LESS . AT THAT TIME ANGLE OF INCIDENCE WIL ALSO BE VERY LESS .AS YOU KNOW PRISM FORMULA IS A RELATION BETWEEN ANGLE OF MINIMUM DEVIATION , ANGLE OF PRISM AND REFRACTIVE INDEX .

Refracting angle of a prism. Also found in: Medical, Encyclopedia. Related to Refracting angle of a prism: angle of emergence. (Opt.) the angle of a triangular prism included between the two sides through which the refracted beam passes in the decomposition of light.
