Question

I wanted to know what is Quantum Pysics

Answer 1

Quantum Physics help us understand the properties of solids, atoms, nuclei, sub-nuclear particles and light.

The word quantum refers to discreteness.

Answer 2

Quantum Mechanics attempts to explain subatomic particles at a nanoscopic level

Step-by-step explanation:

subatomic particles are particles smaller than an atom

a nanoscopic level/scale/nanoscale usually refers to structures with a length scale applicable to nanotechnology, usually cited as 1–100 nanometers. A nanometer is a billionth of a meter. (quantum mechanics is quantum physics)
