ok so I know the formula to calculate the cut off frequency is ?c: 2?aNA / V
in the problem V= 2.405 a=8Mm(Micrometers) NA=0.12 so is ?c: 2?(8x10^-6)(0.12)/2.405
I know the answer is 1254 nm Bu the Problem is that I don't know how to get to that answer on the calculator, what I get on calculator is 1.56673596674e^-6 and I don't know what to do with it I'm using the TI-86
thanks!!!
