Question

What is the difference between angle of deviation and angle of deflection ?

Answer 1

Angle Deflection means the angle by which our subject is deflected or bent by some external force
Light is deflected; means it bounces back on the plane surface when it is bent by a gravitational force. For example, a mirror never reflects the exact sum of light; and it will bounce back on the other side. If a ball is hit on the ground, it will never bounce back to the same spot where it first started. The Law of Thermodynamics states that in deflection that there is a relation to energy and work. The corpuscular theory of light states that the reflection of light helps the deflection of small light particles (corpuscles). The deflections of waves like light consist of reflection and refraction.




​​​​​​Angle of deviation means the angle in change of path .it is same as angle of refraction . If a light ray is refracted by some angle we call that angle angle of deviation
