Question

how do you actually store data into light so it transmits it?

In: Physics

Answer 1

You don’t “store” data into light. The light is the medium which is used to represent the data being transmitted.

You can use light to represent data the same way you use any other material, particle or phenomena – by manipulating its physical properties by whatever means we know how and can measure. With light specifically, we can easily change its direction (what is it pointed at), intensity (how bright is it), frequency (what colour is it), polarisation (what direction is it vibrating), phase (relationship between different parts of the wave frequency) or more.
