Plane mirror

Plane mirror

1. Reflection

2. Reflection of light from smooth & highly polished surfaces

3. What is a Mirror? Simple mirror is actually a plane glass which is silver plated Can we make a Mirror? Plane glass provides the smooth surface Silver coating makes it shiny

4. How to prevent light going through the mirror? Behind the silver coating there is a red paint Red paint also protects the silver coating from getting scratched Red paint prevent the light to pass through the plane glass

5. Smooth surface The ray of light falling on the mirror is the Incident Light

6. Point of incidence The point at which the incident ray strikes the reflecting surface The ray of light bouncing off from the mirror is the reflected ray The line drawn perpendicular to the mirror at the point of incidence is called Normal

7. The ray of light falling on the smooth and highly polished surfaces like mirror is called incident ray The point at which the incident ray strikes the reflecting surface is called point of incidence The line drawn perpendicular to the mirror at the point of incidence is called normal The ray of light bouncing off from the mirror is the reflected ray

8. Angle of incidence & Angle of reflection
