Question | Answer |
---|---|
Reflection | The bouncing back of light into the same medium after striking a smooth surface is called reflection |
rough surfaces | scatter light |
incident ray | The incoming ray of light |
reflected ray | The ray that bounces off the reflecting surface |
normal | The imaginary line that is perpendicular ( 90 ˚) to the surface |
angle of incidence | The angle formed by incident ray and the normal |
angle of reflection | The angle formed by the reflected ray and the normal |
The law of reflection | Angle of incidence (i) is equal to Angle of reflection(r) |
