The angle between the incident ray and the normal is called the angle of incidence . If so, can you explain ehat is angle of refraction ?

Are the angle of incidence , angle of refraction and the normal at the point of incidence on the same plane ?

What is the relation between anlage of incidence and angle of reflection?

What speciality is observed in the value of ratio of sine of the angle of incidence to the sine of the angle of refraction, sin I / sin r ?

Is the angle of refraction greater or lower than the angle of incidence when it goes from air to glass ?

In the figure PQ is a ray Incident on a prism ABC. Complete the ray diagram showing the passage of light. Mark angle of incidence i, angle of emer gence e, angle of deviation delta and angle of re fractions r_1 and r_2
