Question

Classical physics is a good approximation to modern physics under certain circumstances. What are they?

Step-by-Step Solution

Answer

Classical physics will be a good approximation for quantum physics, only for those systems that are composed of large number of particles.

Step 1:

Quantum physics explains different systems at the micro-level. It considers the motion of each and every fundamental particle, that forms the system. On the other hand, classical physics works on the macro level and considers a system made of a large number of particles as one.

Step 2:

Thus, If a system is made of a large number of particles, we can use classical physics, in place of quantum physics.
