Question

How is optics used in our lives?

Answer 1

Answer:

Optics is everywhere, the way you see light, colours, the way things you see.

optics is not applicable to our live, actually it's a definition or explanation to everything that we see.

you see yourself in mirror, your shadow everything is due to reflection and refraction of light and this is where optics comes to explain why things seem the way they are.

Why you see somethings are transparent and some are not. We can tell it by Optics.
