Why is angle of incidence equal to angle of reflection???

Question

Answer

The normal line divides the angle between incident ray and reflected ray into two equal angles

Answer

Because it is law of reflection

Answer

We know that every action has its equal and opposite reaction...so when the incidence ray falls on the mirror it reflects back with equal angle . therefore , the angle of incidence is equal to angle of reflection.

Answer

But there must be some proof why we follow it

Answer

If u want prove there r many practicals for it ask to your teacher he or she will explain with it practical.

Answer

Can we use any other gas in chips packet to prevent rancidity?

Answer

Because light travel in a straight path

Answer

Brother these are just sayings I want a practical proof

Answer

Because it is a law stated by scientist, and laws cannot be questioned. It has to be just followed!!
The simple way to to understand
that in cricket when ball hits the wicket the batsman gets out.
Its a law stated in the book.
Can you question why batsman is given out when ball hits the wickets??

Answer

Angle of Incidence equal to Angle of Reflection

Angle of Incidence:
- The angle of incidence is the angle between the incident ray and the normal (perpendicular line) to the surface at the point of incidence.

Angle of Reflection:
- The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of reflection.

Law of Reflection
- According to the law of reflection, the angle of incidence is equal to the angle of reflection. This law holds true for all types of waves, including light waves.

Explanation
- When light waves strike a smooth surface, they bounce off in a predictable manner. The angle at which the light hits the surface (angle of incidence) is equal to the angle at which it bounces off (angle of reflection).
- This phenomenon can be explained by the principle of conservation of energy and momentum. When light waves interact with a surface, they transfer momentum to it, causing the surface to exert an equal and opposite force on the waves. This results in the reflection of the waves at the same angle.

Visual Representation
- To visualize this, imagine a ball bouncing off a flat surface. The angle at which the ball hits the surface is equal to the angle at which it bounces off. Similarly, light waves behave in the same way when they interact with a reflective surface.

In conclusion, the angle of incidence is equal to the angle of reflection due to the law of reflection, which is a fundamental principle governing the behavior of waves when they interact with surfaces.
