Question

formula for the refractive index of a prism and explain its terms.

Answer 1

Answer:

sin(A+D)/2/sin (A/2)=refractive index of prism

Explanation:

A is angle of prism

D is angle of minimum deviation

Answer 2

The formula for the refractive index of a prism =

                              n = $sin(\frac{A+D}{2} )/sin(\frac{A}{2} )$

• The extent of bend in the light rays when entering into another medium is measured by an index called refractive index.

• A prism is a solid geometric figure with equal and parallel rectilinear figures on all of its end sides. The "Dispersion of light rays" is the main phenomenon that occurs in a prism.

•    Refractive index of a prism (n) = $sin(\frac{A+D}{2} )/sin(\frac{A}{2} )$

           Where,

            D is the angle of minimum deviation.

            A is the angle of prism.
