A ray of light passes through an equilateral prism such that the angle of incidence is equal to the angle of emergence and each of these equal to 3/4 of the angle of the prism. The angle of deviation is A thin prism p of refracting angle 3 degree and refracting index 1.5 is combined [...]

A ray of light suffers a minimum deviation when incident on an equilateral prism of refractive index root 2. The angle of incidence is : A ray of light suffers a minimum deviation when incident on an equilateral prism of refractive index root 2. The angle of incidence is : November 9, 2020 Category: Chapter [...]

A ray of light is incident at an angle of 60∘ on the face of a prism having refracting angle 30∘. The ray emerging out of the prism makes an angle 30∘ with the incident ray. The refractive index of the prism is f2 = −10cm and f3 ​ = +30cm). The position of final [...]

A thin prism p of refracting angle 3 degree and refracting index 1.5 is combined with another thin prism Q of refractive index 1.6 to produce dispersion without deviation. The angle of prism Q is. A thin prism p of refracting angle 3 degree and refracting index 1.5 is combined with another thin prism Q [...]

A glass prism of refractive index 1.5 is immersed in water (refractive index 4/3). A light beam normally on the face AB is totally reflected to reach on the face BC if A glass prism of refractive index 1.5 is immersed in water (refractive index 4/3). A light beam normally on the face AB is [...]

An isosceles prism of angle 120^∘ has a refractive index 1.44. Two parallel rays of monochromatic light enter the prism parallel to each other in air as shown. The rays emerging from the opposite face An isosceles prism of angle 120^∘ has a refractive index 1.44. Two parallel rays of monochromatic light enter the prism [...]

A square card of side length 1 mm is being seen through a magnifying lens of focal length 10 cm. The card is placed at a distance of 9 cm from the lens. The apparent area of the card through the lens is f2 = −10cm and f3 ​ = +30cm). The position of final [...]
