I would definitely look at the impressionists as part of a study of light, or even just to appreciate what they did as painters.
If you look at Monet, as seen here, you can just see the brightness and vivacity of what he painted, it just seems 'real' even though the actual drawings are not hyper realistic styling.
In comparison a slightly earlier painter,
[link] paints also fabulous landscapes but they have a slightly different colour cast to them, much heavier and less 'real' although the actual details are much more 'realistic' such as the details in the sea.
Neither of course is wrong, how can Art be wrong, but both have different outlooks and something can be learned from both of them.
I of course am a fan of both of these painters, hence why I chose them as examples, but if you don't like what they do, go out and find painters you do like
If you're interested in Art I would definitely encourage you to look up art history in your own time. Study in more detail the things you like, gloss over the stuff you don't, and just enjoy the work. If you don't understand it perhaps look in more detail. There are some Art movements like dadaism that make me go "wtf" and I understand what they meant but I don't like the work. So not all of it will be "ooo prettty".
The impressionists are favourites of mine in general, for what they stood for as people, and what they created, and I do have a minor obsession with them, but there are other movements I know nothing about because I am not interested in them. We are a sum, as artists, of all that interests us.
