Answer:
Explanation:
The resolving power of the microscope is dependent upon the objective lens. It can be measured by the ability of the lens to differentiate between the two lines or points on the specimen under observation. The more the resolving power the smaller will be the distance between the two lines or points that can be distinguished.
The following are the two ways that can be used to enhance the resolving power on the microscope:
Using a lens that has a higher aperture.
Decreasing the amount of light being entered into the microscope that means using light of less wavelength.
