Question

what is quantum physics????

Answer 1

Heya!
_______________________
Quantum physics is the study of the behaviour of matter and energy at the molecular, atomic, nuclear, and even smaller microscopic levels. In the early 20th century, it was discovered that the laws that govern macroscopic objects do not function the same in such small realms. Now this is a very vast concept and just for your understanding, i am giving the ideas represented by this theory in five points. If you understand these points, it should be enough for you.

1) Energy is not continuous, but comes in small but discrete units. 
2) The elementary particles behave both like particles and like waves. 
3) The movement of these particles is inherently random.
