First – if you are looking through binoculars, the image from the objective is just being split before reacting the head piece, so the imagine is only being magnified by either the left or right eyepiece, not both.
Second and third – recall that resolution is the ability to differentiate between two points. In order for a light microscope to resolve two points, those two points must be at least as far away (in distance) as the wavelenth of the light passing through them on the microscope stage. Visible light has wavelengths from 700nm (red) to around 400nm (violet). Anything close together than 400nm cannot be resolved using light microscopy because the photons “bounce around” too much within the light path to provide a good imagine. Electrons have tiny, tiny wavelengths, which is why electron microscopy is so much more powerful than light microscopy. That answers question three, so you should be able to answer question two…if red’s wavelength is 700nm, than two points must be at least 700nm apart to be resolved. Violet light has a wavelength of 400, so it can resolve up to 400nm. Good luck, and I hope this helps you!
