What are the important points of Graphs of Net deviation Vs angle of Incidence ???
Answers
Answer:
Explanation:
The relationship between the incident angle and the refraction angle is that for any reflected light ray the angle of incidence equals the angle of reflection. I=R. 3. You were directed to measure the angle of reflection when the ray was incident on either side of the normal to the surface of the mirror.
f you have ever looked at a white light being shined into a prism, the main thing you probably noticed is it being turned into a rainbow. However, did you notice that the light didn't travel straight through the prism? The light changes direction when it enters the prism, and it changes again when it leaves. This bending of light isn't something that's unique to prisms. It's a common occurrence in translucent and transparent materials. We have even come up with unique names for the angles at which the light enters and travels through the material. The angle at which the light enters is called the angle of incidence.
HEY MATE HERE IS YOUR ANSWER :-
Important points :
At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. This line is known as a normal line (labeled N in the diagram). The normal line divides the angle between the incident ray and the reflected ray into two equal angles.
Angle of deviation change with angle of incidence :
The angle through which the emergent ray deviates from the direction of incident ray is called angle of deviation 'd'. As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased.
