!! RADIATION WAVES !!

Whenever there is aFRICTION and MOVEMENT between two objects , u'll get HEAT..
The reason is because , movement of MOLECULES and HEAT are really one and the same ,
bt we know that MOVEMENT is a form of ENERGY , so it follows that HEAT itself must
also be a form of ENERY..

That's why Heat , just like Energy , is measured in Joules.......................

In Heat Transfer :
= Conduvtion
= Convection
= Radiation
