Answer 1

~~You don’t have triple or quadruple cameras, you have triple or quadruple *lenses*.~~ The lens is the part of the camera that focuses light.

Lenses are what allows a camera to zoom in, for example.

Traditional cameras have the ability to swap lenses, but it isn’t practical to swap lenses on a phone. Instead, phone manufacturers put multiple lenses on permanents for different purposes.

This is why your phone is able to take photos at different levels of zoom or wideness.
