, LIGHT
- It is a form of energy that enables us to see.
- Light always travels in straight line.
- Light makes shadow. Without light Shadow is not possible.
- Light has the maximum speed in this world. Its value is 3x108 m/s.
Reflection
Coming back of light rays to the same medium when they fall on a
surface.
Laws of Reflection
1) Angle of Incidence = Angle of Reflection
2) Incident ray, normal at the point of incidence are
reflected ray all lie in the same plane.

, Types of Mirrors
1) Plane Mirror
- Object and Image are at equal distance from Plane Mirror.
- If object is real, then image will be virtual and vice versa.
- Size of image is equal to size of object.
Lateral Inversion – The right side of the object appears left
side of the image and vice-versa.
Uses - Looking Glass, Periscope, Kaleidoscope etc.
