Question

Models are particularly useful in relativity and quantum mechanics, where conditions are outside those normally encountered by humans. What is a model?

Short answer

Models are mathematical and Physical representations of concepts, ideas, or theories for better understanding. Before converting it into a device, models are designed.

Step-by-step solution

Definition

A model is a display of something that is very hard or impossible to represent directly.

Its accuracy lies in limited conditions.

It should verify experimental data.

Example

For Example: In Atom, electron orbits around the nucleus, but one can’t see it directly with naked eyes because it is very small. But one can draw a structure of an atom for explanations.
