By placing the prism in minimum deviation position, images of the spectrum

Why do we keep the prism in minimum deviation position while studying the spectrum ? It make the spectral lines of different colours

When light of wavelength lambda is incident on an equilateral prism kept in its minimum deviation position, it is found that the angle of deviation equals the angle of the prism itself. The refractive index of the material of the prism is

A light ray is incident on a prism in minimum deviation position and suffers a deviation of 40^@ . If the shaded half of the prism is removed off, then the same ray will suffer a deviation of

A ray of light is incident on the face o a prism placed in minimum deviation position.If the anle of prism is 60^@ and deviation produced is 34^@ ,find the angle of incidence and refractive index.

A light ray is incident upon a prism in minimum deviation position and suffers a deviation of 34^(@) . If the shaded half of the prism is knowked off, the ray will

A light ray is incident upon a prism in minimum deviation position and suffers a deviation of 34^(@) . If the shaded half of the prism is knocked off, the ray will

A ligh ray is incident upon a prism in minimum deviation position and surfers a deviation of 34^(@) . If the shaded half of the prism is knocked off, the ray will

A light ray is incident upon a prism in minimum deviation position and suffers a deviation of 34^(@) . If the shaded half of the prism is knocked off, the ray will

A ray light is incident on a 60^@ prism at the minimum deviation position.The angle of refraction at the face (i.e.incident face)of the prism is:
