Reflection of Light
⭐ MasteredReflection happens when light bounces off a surface. The angle at which light hits a mirror equals the angle at which it bounces off.
A smooth mirror gives a clear reflection, while a rough wall scatters light in many directions.
All about Reflection of Light
Reflection happens when light bounces off a surface. The angle at which light hits a smooth surface equals the angle at which it leaves.
Smooth surfaces such as mirrors reflect light clearly, while rough surfaces scatter it in many directions.
Mirrors are the best reflectors because they are smooth and shiny. When light hits a mirror, it bounces back at the same angle at which it arrived. This rule is called the law of reflection, and it is why you can see yourself in a mirror.
Periscopes use mirrors to let people see over obstacles, and road signs use reflective materials so that drivers can see them at night.

Frequently asked questions about Reflection of Light
Why does a mirror give a clear image?
It is smooth, so it reflects light in an organised way.
What is the angle rule for reflection?
The angle of incidence is equal to the angle of reflection.
