Question

define thin prism of an deviation ?​

Answer 1

Answer:

Thin prisms are used for optometric correction of strabismus (a misalignment of the axes of the eyes). The deviation is measured in prism diopters. A prism of 1 diopter deviates a beam by 1 cm at 1 m. For small deviations: ( in 0.01 radians)

Answer 2

Answer:

A beam of light is incident on a prism with refractive index n.

Explanation:

• A thin prism is a transparent, triangular prism with an extremely modest apex angle of less than 10.

• When both of these little numbers are rounded off and the equation is rearranged, the prism formula for a narrow prism is obtained.
• The deviation of the ray is the acute angle formed by the beam's directions as it enters and exits the prism.
