Reflection

Well, as said we will be first learning about Reflection and Refraction.......

• Reflection

Reflection occurs when light bounces off objects.  How much reflection depends upon how even the surface is.  If the surface is rough, the light scatters.  If the surface is smooth and flat, the light will bounce off it at equal angles.  That is why a flat mirror reflects a good likeness of the object being reflected.

Well, there are Laws of Reflection, which are as follows...

1. The angle of incidence is equal to the angle of reflection.
2. the incident ray, the normal ray and the emergent ray, all lie on the same plane in any conditions.

Look at the images below............

Now, the first image is of the light reflecting through a plain, smooth and shiny surface while the second image is of light reflecting from a crooked, uneven and crumbly surface.

It is this factor which enables us to see light which is reflected from the objects we see in our surroundings.

So this was all about reflection....In the next post I will be telling you all about Refraction!
