Do we use optics in other branches of physics ?

[Peter25samaha]

it is necessary to study the branch physics optics to use it in high energy physics , quantum mechanics and particle physics? To be more be more precise do use optics at all in these 3 ?

Well if you read the wikipedia article on optics, you begin to see that optics math techniques and concepts are used over and over in other areas of physics:

Nearly all modern experiments about quantum mechanics use light in some way, often the experiments are a huge collection of optical elements.

Experiments in high-energy physics / particle physics can use optics to focus light on detectors, for example. It is not necessary to know it to understand particle physics, however.In the time you spend trying to classify everything, you could probably learn a lot about physics...
