they involve fundamental concepts that are unavoidable by the thoughtful person.
Exposure means how light or dark the image you took with your camera will come out which is determined by the exposure triangle which contain 3 camera settings(aperture, iso, and shutter speed)
as aperture increases the f-stop values, the lens shuts. as it decreases the lens opens
light is a factor in the exposure of the photograph. aperture must be calibrated so the image will be clear and focused
I'm not sure on the last one but I know that when the aperture is low itll be a fast lens and when its higher itl be a slow lens
