== == When using a light microscope you encounter diffraction. (Visible light behaves like a wave, with a wavelength of about 300 to 900 nanometres). We say that light diffracts when its wavelike behaviour makes it bend around obstacles, or spread out. If the obstacle is much larger than the wavelength of the incoming wave, the spreading-out will be smaller. If the gap is smaller than the wavelength, then the spreading-out will be very large. In a light microscope, the light waves will spread out whenever they pass through a lens, or any sort of obstruction. The primary lens in most microscopes is of much bigger than 300-900 nanometres, so the angle by which light waves diverge is really quite small. However, it is not zero the light waves do spread out a little bit, and the result is that the visual field is always a bit blurry. It is impossible for an ordinary light microscope to avoid this problem, so they can never see structures smaller than about 500 nm.

What is the resolving power for an electron microscope?
The resolving power of an electron microscope is typically around 0.2 nanometers, which is much higher than that of a light microscope. This allows electron microscopes to visualize objects at the atomic scale.
What limits the resolving power of an electron microscope?
The resolving power of an electron microscope is limited by the wavelength of the electrons being used, which is much smaller than that of visible light. Additionally, aberrations in the electron optics and sample distortion can also limit the resolution.
What factors determine the resolving power of a microscope?
The resolving power of a microscope is determined primarily by the numerical aperture of the lens and the wavelength of light used for imaging. A higher numerical aperture allows for better resolution. Additionally, the quality of the optics and the design of the microscope also play a role in determining its resolving power.
What is the resolving power of an electron microscope?
The resolving power of an electron microscope is typically between 0.1 to 0.3 nanometers, which is much higher than that of a light microscope. This allows electron microscopes to visualize structures at the atomic level.
What does resolving power of a microscope mean?
The resolving power of a microscope refers to its ability to differentiate between small details in an image. It is determined by the numerical aperture of the lens and the wavelength of the light being used. A higher resolving power means that the microscope can distinguish between finer details in the specimen being observed.
Explain the relationship between the resolving power of the microscope and the wavelength of the light being used?
The resolving power of a microscope is inversely proportional to the wavelength of light being used. This means that as the wavelength of light decreases, the resolving power of the microscope increases. Shorter wavelengths can resolve smaller details, allowing for higher magnification and clearer images.
What is the resolving power of a scanning electron microscope?
The resolving power of a scanning electron microscope is typically around 1-5 nanometers, depending on the specific model and parameters used. This high resolution allows for detailed imaging of nanostructures and surface features.

What is the resolving power of a compound microscope?
The resolving power of a compound microscope is the ability to distinguish two closely spaced objects as separate entities. It is determined by the numerical aperture of the objective lens and the wavelength of light being used. The higher the resolving power, the greater the level of detail that can be observed in the specimen.
What property of a microscope affects the sharpness of its images?
The resolving power of a microscope determines the sharpness of its images. Resolving power refers to the microscope's ability to distinguish between two points that are close together. A microscope with higher resolving power will produce clearer and sharper images.
Which has the least resolving power?
A transmission electron microscope.
