The correct answer is C. Both S1 and S2 are true.
A microscope is an instrument that uses lenses to magnify small objects. The two main functions of a microscope are to magnify the object and to resolve the object. Magnification is the enlargement of an image, while resolution is the ability to distinguish between two closely spaced objects.
A microscope can magnify an object up to 1000 times or more. This allows scientists to see objects that are too small to be seen with the naked eye. The resolution of a microscope is determined by the wavelength of light and the numerical aperture of the objective lens. The numerical aperture is a measure of the light-gathering ability of the lens.
The higher the numerical aperture, the better the resolution of the microscope. A microscope with a high numerical aperture can resolve objects that are very close together. This is important for studying the fine details of cells and other small objects.
In conclusion, both S1 and S2 are true. A microscope magnifies objects and resolves objects.
