What is emergence angle?

What is incidence angle ?

In an experiment for determination of refractive index of glass of a prism by i-delta , plot it was found thata ray incident at angle 35^circ , suffers a deviation of 40^circ and that it emerges at angle 79^circ . In that case which of the following is closest to the maximum possible value of the refractive index?

Obtain the relation between incidence angle, emergence angle, prism angle and deviation angle for refraction through prism

In the above figure (ray diagram), state angle of incidence, angle of emergence and angle of deviation.

For a prism, angle of prism is 60^@ and it.s refractive index is 1.5, find (1) angle of incidence corresponding to the angle of minimum deviation and (2) angle of emergence for angle of maximum deviation.

A diverging beam of light from a point source S having devergence angle alpha , falls symmetrically on a glass slab as shown. The angles of incidence of the two extreme rays are equal. If the thickness of the glass slab is t and the refractive index n, then the divergence angle of the emergent beam is

In a ballistics demonstration a police officer fires a bullet of mass 50.0 with speed 200 ms^(-1) on soft plywood of thickness 2.00 cm . The bullet emerges with only 10 % of its initial kinetic energy. What is the emergent speed of the bullet ?

A ray incident at an angle 53^(@) on a prism emerges at an angle 37^(@) as shown. If the angle of incidence is made 50^(@) , which of the following is a possible value of the angle of emergence?

What is used as emergency contraceptive ?
