Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following best defines resolution in an optical instrument?
The ability to magnify an object.
The clarity and sharpness of an image.
The ability to distinguish between two closely spaced objects.
The total light gathering power of the instrument.
2. What is the primary factor limiting the resolution of a light microscope?
The focal length of the objective lens.
The wavelength of light used.
The numerical aperture of the condenser.
The magnification of the eyepiece.
3. The Rayleigh criterion states that two objects are just resolvable when the center of the diffraction pattern of one object is directly over the first minimum of the diffraction pattern of the object.
4. Electron microscopes have significantly higher resolution than light microscopes because electrons have a much smaller than photons.
5. Explain the concept of 'diffraction limit' in relation to optical resolution.
6. Increasing the numerical aperture of an objective lens will decrease its resolving power.
True
False
7. The resolution of a telescope is primarily determined by the diameter of its objective lens or mirror.
True
False
8. Observe the image of the microscope below. How does the objective lens contribute to the resolution of the image seen through the microscope?
