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 , then a bacterium in diameter will not be visible.
C If the wavelength of light is , then two membranes apart will be visible as two distinct membranes.
D Using visible light of a longer wavelength, such as red light, will improve the resolution.
