Question

What is quantum ralm ?

Answer 1

The quantum realm, also called thequantum scale, is a term of art in physics referring to scales wherequantum mechanical effects become important when studied as an isolated system. Typically, this means distances of 100 nanometers (10−9meters) or less or at very low temperature.

Quantum realm is a term of art in physics referring to scales wherequantum mechanical effects become important when studied as an isolated system. Typically, this means distances of 100 nanometers (10−9 meters) or less or at very low temperature. More precisely, it is where the action or angular momentum is quantized.
