# When is it necessary to use relativistic quantum mechanics?

In Physics, relativistic quantum mechanics is used for explaining the motion of those systems that have a size which is comparable to that of a hydrogen nucleus and are travelling at speeds comparable to the speed of light.

See the step by step solution

## Step 1:

Quantum physics deals with a system that is comparable to a hydrogen nucleus or is smaller than that, in terms of size. Relativistic effects need to be considered if a system travels at speeds comparable to the speed of light.

## Step 2:

Thus, it can be concluded that relativistic quantum physics is applicable for very small objects travelling at very high speeds.
