M. Tech. Electronics Engineering

The deviation angle in a prism depends upon: 1. Refractive index of the prism: The refractive index depends on the material and the wavelength of the light. The larger the refractive index, the larger the deviation angle. 2, Angle of the prism: The larger the prism angle, the larger the deviation...

The deviation angle in a prism depends upon: 1. Refractive index of the prism: The refractive index depends on the material and the wavelength of the light. The larger the refractive index, the larger the deviation angle. 2, Angle of the prism: The larger the prism angle, the larger the deviation angle. 3. Angle of incidence: The deviation angle depends on the angle that the beam enters the object, called angle of incidence. The deviation angle first decreases with increasing incidence angle, and then it increases. There is an angle of incidence at which the sum of the two deflections is a minimum. The deviation angle at this point is is called the "minimum deviation" angle, or "angle of minimum deviation".[1] At the minimum deviation angle, the incidence and exit angles of the ray are identical. This is a consequence of the principle of time reversibility; if the incidence and exit angles were not identical, then reversing the paths (exit becomes entrance, and vice versa) would indicate erroneously that there were two incidence angles resulting in minimum deviation. One of the factors that causes a rainbow is the bunching of light rays at the minimum deviation angle that is close to the rainbow angle. A convenient way to measure the refractive index of a prism is to direct a light ray through the prism so it produces the minimum deviation angle. read less

The angle of minimum deviation does not affect wavelength of the incident light, but it is vice versa. The wavelength of light determines the refractive index of the prism and this affects the angle of minimum deviation according to the formula n=sin((A+D)/2)/sin(A/2). Hope it is clear!

Actually wavelength of light affect angle of deviation:) Explanation: With increase in wavelength deviation decreases. e.g.: Deviation for red light is least while maximum for violet.

Angle of min deviation decreases with the increase of wavelength of light.

A prism is a wedge-shaped body made from a refracting medium bounded by two plane faces inclined to each other at some angle. The two plane faces are called are the refracting faces and the angle included between these two faces is called the angle of prism or the refracting angle.

A convenient way to measure the refractive index of a prism is to direct a light ray through the prism so it produces the minimum deviation angle. This yields a simple formula:[2] n_\lambda={\sin ({A+D_\lambda \over 2}) \over \sin ({A \over 2})} where n is the refractive index at a wavelength ? , D is the angle of minimum deviation, and A is the internal angle of the prism. The angle of minimum deviation is attained when the angle of incidence and angle of emergence for a ray of light being refracted through a prism, are equal. It may be noted that minimum deviation in a rectangular slab is zero as both the surfaces separating two media are parallel, whereas, in a prism they are inclined to each other.A convenient way to measure the refractive index of a prism is to direct a light ray through the prism so it produces the minimum deviation angle.
