Q11MCell StructureFree sample

Which statement about the light microscope is correct?

Options

A   As the smallest distance to see two points as distinct separate points decreases, the resolution also decreases.
B   If the resolution is 220 nm220\ \text{nm}, then a bacterium 0.2 μm0.2\ \mu\text{m} in diameter will not be visible.
C   If the wavelength of light is 600 nm600\ \text{nm}, then two membranes 300 nm300\ \text{nm} apart will be visible as two distinct membranes.
D   Using visible light of a longer wavelength, such as red light, will improve the resolution.
