When something is observable, you can see it or notice it — it is not hidden away. Scientists like this word: a change is observable if you can watch it or measure it, even if it is small. In ordinary talk people more often say you can see it or it is noticeable; observable sounds a little more careful, like a classroom or a lab. Though actually, in physics observable is also a noun: a thing you are allowed to measure, like speed or temperature. Most meet the adjective first, and that is the meaning here: able to be seen or noticed.
