PHYSICS- CAMBRIDGE -CHAPTER 7 LIGHT

1. 7.3 REFLECTION OF LIGHT
SIR.MUHAMMAD

2. SIR.MUHAMMAD – VIII CAMBRIDGE
When light reaches a
surface it can be absorbed
,transmitted or reflected.
If the light is reflected,the
ray leaves the object and
keeps on travelling

3. Reflection of light
Reflection of light:
Bouncing off (returning
back) the light ray when it
falls on a reflecting
surfaces as mirrors

4. Key words related to reflection
Angle of incidence : the
angle between the incident
light ray and the normal
Angle of reflection : the
angle between the reflected
light ray and the normal

5. The law of light reflection
Angle of incidence = Angle of reflection

6. SIR.MUHAMMAD – VIII CAMBRIDGE
When the light ray falls
perpindicular to the reflecting
surface , it will reflect on itself
BECAUSE
THE ANGLE OF INCIDENCE =THE ANGLE
OF REFLECTION = ZERO
