Seeing through things

What I learnt...

In my science I have learnt 

What opaque means-it means that no light can go through it and it makes a shadow.

What Translucent means- some light can go through.

What transparent means- all light can go through

Light bounces off shiny surfaces like mirrors.

Some bright things reflect back at you.

Light travels faster then anything.

Light travels in a straight line.

Shadows are from the opposite side of the sun.
