The two dots P1 and P2 shown in each of the following diagrams, I, II, III and IV denote the position of two pins in respect of distance and direction for performing an experiment on tracing the path of a ray of light passing through a rectangular glass slag. In which one of the four cases, one is likely to get best result
Answers
The incidence angle and the distance between two dots is appropriate.
so,correct option is c.
In II diagram one is likely to get the best result
The incidence angle and the distance between the two points are both suitable. The angle of incidence should be between 30° and 60° for the greatest results. As a result, dots P1 and P2 should be on the incident ray, forming a 30 to 60 degree angle with the normal.
Incidence ray - the incident ray is the ray of light that falls on the surface AB. Reflected ray refers to an incident ray that bounces back in the same medium after contacting a reflecting surface. The angle of incidence is defined as the angle formed between the incident ray and the normal. The angle of reflection is defined as the angle formed between the reflection beam and the normal.
