Question

What is quantum mechanics physics ​

Answer 1

Answer:

Quantum mechanics is the branch of physics relating to the very small. ... At the scale of atoms and electrons, many of the equations of classical mechanics, which describe how things move at everyday sizes and speeds, cease to be useful. In classical mechanics, objects exist in a specific place at a specific time.

Today, the most precise clocks in the world, atomic clocks, are able to use principles of quantum theory to measure time. They monitor the specific radiation frequency needed to make electrons jump between energy levels.
