LAW OF REFLECTION – “Magic of Mirror”
Explains in a simple term, how reflection works. How do we see our face when we look into the mirror? Ever wondered why? And wanted to know, then come on.
- When ray/light (all objects emits ray ) hits the smooth polished surface(water, mirror, glass, steel plate etc) it will bounce back the ray. Thus reflection works. Like a ball hits the wall and bounce back.
- But why some object like water, mirror, glass, steel plate etc reflect and other like wood, wall, brick etc not. It is because the wood, brick, wall has a rough surface and therefore cannot reflect.
- Once the light/ray hits the surface off a silver mirror, the light cannot travel through the silver (a paste-like substance painted at the back of the mirror), but the silver also cannot absorb the light. As a result, the light “bounces off” of the surface of the silver and returns to your eye, which is why you can see yourself in a mirror.
- We would not be able to see anything at all – tree, car, school, friends everything else in the world without the reflected light.
- Wonder why we cant see in the dark, because of lack of light for reflecting surface to reflect it.
Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.
For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection. Like we see in this picture, where this water droplet disturbs the base water thus the reflection was scattered.
Reflection: he throwing back by a body or surface of light, heat, or sound without absorbing it
Ray: each of the lines in which light (and heat) may seem to stream from the sun or any luminous body, or pass through a small opening
Diffuse: lacking clarity or conciseness
Specular: relating to or having the properties of a mirror
Scatter: throw in various random directions
