But you aren't seeing the membranes. Your simply looking at the lines of the cell which you can see. And which are 300nm apartResolution means the ability to distinguish between two different points. With a resolution less than 7 nm, you won't be able to differentiate the membrane from its surroundings, you won't see it.

Which of the following can result in heart failure?
1 increase in blood pressure
2 deposits of fatty material in arteries and veins
3 reduced oxygen supply to cardiac muscle
4 increased risk of blood clotting
A 3 and 4 only
B 1, 2 and 3 only
C 1, 2 and 4 only
D 1, 3 and 4 only
But resolution= wavelength / 2. So the resolution of a 600nm wavelength should give a 300nm resolution. And since resolution is the ability to distinguish between 2 points then 2 membranes 300 nm apart should be seen as separate points..
Right?
