We Have A Right-angled Isosceles Prism. Its Refracting Index Is 1.5. If A Ray Is Incident Normally On One Of The Two Perpendicular Surfaces Which Of The Following Phenomena Will Take Place?    

Angle of minimum deviation for a prism of refractive index 1.5 is equal to the angle of prism. The angel of the prism is:

(Given cos 41^o ≈ 0.75) 

A prism (μ = 1.5) has the refractive angle of 30^o. The deviation of a monochromatic ray incident normally on its one surface will be (sin 48^o36’ = 0.75):  

A thin prism P₁ with angle 4^o and made from glass of refractive index 1.54 is combined with another thin prism P₂ made from glass of refractive index 1.72 to produce dispersion without deviation. The angle of the prismP₂ is:

Two identical prisms 1 and 2, each with angles of 30^o, 60^o and 90^o are placed in contact as shown in figure. A ray of light passes through

The combination in the position of minimum deviation and suffers a deviation of 30^o. if the prism 2 is removed, then the angle of deviation of the same ray is;

The angle of a prism is 30^o. The rays incident at an angle of 60^o at one refracting face suffer a deviation of 30^o. Then the angle of emergence is:

A parallel beam of white light falls on a convex lens. Images of blue, yellow and red light are formed on the other side of the lens at a distance of 20 cm, 20.5 cm and 21.4 cm respectively. The dispersive power of the material of the lens will be: 

A thin prism made of glass is dipped in water; then minimum deviation with respect to air by it will be:

A prism has a refracting angle 60^o. A ray of given monochromatic light suffers minimum deviation of 38^o in passing through the prism. The refractive index of the material of the prism is:

A liquid is placed in a hollow prism of angle 60^o. If angle of minimum deviation is 30^o, what is the refractive index of the liquid?     

A beam of light consisting of red, green and blue colours is incident on a right-angled prism. The refractive indices 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:
