Rays of red and blue light are ncident on a gien prism.Explain,which will have the larger value of `delta_m` the angle of minimum deviation.

Discuss the phenomenon of refraction through a prism and prove that for a prism: mu=(sin(A + delta_m)//2)/(sin A//2) ,where A is anle of prism, mu s refractive index of the material of prism and delta_m is the ngle of minimum deviation.

Two beams of red and violet colours re mde to pass separaterly through a prism (angle of prism is 60^@ ).In the position of minimum deviation,the angle of refraction will be

Three light rays red, green and blue are incident on a right angled prism 'abc' at face 'ab'. The refractive indices of the material of the prism for red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively. Out of the three which colour ray will emerge out of face 'ac'? justify your answer. Trace the out of the face 'ac'? Justify your answer. Trace the path of these rays after passing through face 'ab'.

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^@ . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^@ . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light.

The following table gives the value of theangle of minimum deviation for different values of theangle of incidence for a triangular prism. . For what value of the angle of incidence,is the angle of mergence likely to be equal to the angle of incidence?

A ray of light is incident on a prism ABC of refractive index sqrt3 as shown in Fig.3.14. Find the angle of incidence for which the deviation of light ray by the prism ABC is minimum. .

A beam of light consisting of red, green and blue and is incident on a right angled prism. The refractive index of the material of the prism for the above red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively. The prism will : .

Draw a ray diagram to show the refraction of light through a glass prism. Hence obtain the relation for the angle of deviation in terms of the angle of incidence, angle of emergence and the angle of the prism.
