Light

He skips and trots 

Hist and hops

Bounces and slides of animal's hide 

Light is cool

It refracts and scatters 

Leaving a room

It leaves how it came 

This is a rule of thumb 

The angle at which it came is always the angle at which it goes out 

Light makes colours

Purple, red, blue

It might seem false

But it is very true

Once light bounces based on how it refracts 

It gets a colour on which it acts

Red is most common

In the visible light 

Not all light is visible to us 

Some waves are too long 

While others are too short , or too harmful

Some can harm and also save

Some like gamma kill cancer cells 

But might cause it on its own

Light is cool

It can jump and bounce

It is good and bad

But is always a lad
