Have you ever used an SLR camera with a zoom lens? the focal lengths are marked on the lens barrel and align with a pointer on the zoom adjustment, you can see the FOV change as you zoom in and out. A point and shoot camera might have the focal length range printed on the lens housing, and you can zoom from one to the other and see what happens.
(shorter focal length = wider FOV)
