A monochromatic ray of light is made to fall on a normal `60^@` prism under minimum deviation condition.What is the relatin between the angle of incidenc eand the angle of emrgence?

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:

A ray of light falls on a mirror normally.What are the values of the angle of incidence and the angle of refelection?

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.

What is the angle of incidence when incident ray falls normal to the mirror?

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.

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.

A parallel monochromatic beam of light is incident normally on a narrow slit.A diffraction pattern is formed on a screen placed perpendicular to the direction of the incident beam.At the first minimum of the diffraction pattern,the phase difference between the rays coming from the two edges of the slit is

A ray of light suffers minimum deviation,while passing through a prism of refractive index 1.5 and refracting angle 60^@ ,calculate the angle of deviation and angle fo incidence.

A ray of light passing through an equilateral traingular glass prism from air undergoes minimum deviation,when angle of incidence is 3//4 of the angle of prism.Clculate the speed of light in the prism.

What is the angle of reflection when a ray of light is incident normally to the mirror?
