Is light and optics the same

"Optics" is one field of study in Science. It's the branch of Physics that involves

the behavior and properties of light, including its interactions with matter and the

construction of instruments that use or detect light.

So, light is the relatively skinny sliver of the electromagnetic spectrum that we can

see, and Optics is the science that studies it.

Optics have some qualities as light but they do not have the same definition. But they do have a lot to do with each other and their functions.
