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 the context of scientific instruments?
The ability to magnify an object.
The ability to distinguish between two closely spaced objects.
The clarity of an image.
The total magnification power of a lens.
2. Which of the following factors generally improves the resolution of an optical microscope?
Using a longer wavelength of light.
Decreasing the numerical aperture of the objective lens.
Increasing the refractive index of the medium between the specimen and the objective lens.
Reducing the intensity of the light source.
3. The theoretical limit of resolution for an optical microscope is approximately half the of the light used.
4. Electron microscopes have a much higher than optical microscopes because they use electrons, which have a much shorter .
5. Explain, in your own words, why a higher resolution is crucial in scientific research, providing an example.
6. Observe the diagram of the microscope below. Identify one component that directly influences the resolution and explain how it does so.
7. The smaller the resolvable distance between two points, the higher the resolution.
