In my simulation it did act like a low pass filter so it definitely is one!

please tell me if the following is correct:
this circuit works as a low pass filter because since Zcap = 1/jwC
when w is low the impedance is high so the current flows through R1. this means the current will go to the inverting terminal of the op amp (after joining with the output from the opamp?)
however if w is high the impedance is low which means current will flow to the capacitor which charges up so less current goes to the op amp?
please help a struggling physicist who is taking an electronics course!
thank you
