6. WHAT IS LIGHT??
Light is a form of energy that enable
us to see object in our surrounding or
light gives us the sensation of vision.

7. Light is an electromagnetic
wave

8. Light travels in straight path

9. Light is reflected from all
the surfaces

10. WHAT IS REFLECTION
When light rays fall on an
object their direction
changes and they turn back.
This is called the
reflection of light.

11. LAWS OF REFLECTION

12. INCIDENTAL RAY
The incoming light ray
from a light source, which
Stikes or falls on any surface,
Or falls on any surface, is called
Incidental ray.

13. REFLECTED RAY
The reflected ray are the rays that
bounce after falling On a surface .

14. NORMAL
It is an imaginary line drawn perpendicular
to the surface between the INCIDENT RAY
and REFLECTED RAY.

16. LAWS OF REFLECTION
● Angle of Reflection= Angle of Incidence
● The Incidental ray, Reflected ray,
Normal all lies on the same plane.

17. TYPES OF REFLECTION

18. When light falls on an object or a surface, the light
reflects in two way so, there are two types of reflection.
1. Regular Reflection
2. Diffused Reflection
When light falls on an object or a surface, the light
reflects in two way so, there are two types of reflection.
1. Regular Reflection
2. Diffused Reflection

19. DISPERSION OF LIGHT

20. When a white light ray falls on a surface
of prism,it splits into 7 different colors of
light emite from another surface of prism.
This phenomenon is call dispersion of light
