Verified step by step guidance

Understand the concept of resolution in microscopy: Resolution is the ability of a microscope to distinguish two close points as separate entities. The higher the resolution, the clearer the details of the specimen.

Compare the principles of light microscopy and electron microscopy: Light microscopy uses visible light to illuminate specimens, while electron microscopy uses a beam of electrons, which have a much shorter wavelength than visible light.

Relate wavelength to resolution: According to the Abbe diffraction limit, the resolution is inversely proportional to the wavelength of the illuminating source. Shorter wavelengths provide higher resolution.

Apply the concept to electron microscopy: Since electrons have a much shorter wavelength than visible light, electron microscopes can achieve a much higher resolution than light microscopes.

Conclude the comparison: Based on the principles of resolution and the wavelengths used, electron microscopy has a superior limit of resolution compared to light microscopy, making the statement 'Light microscopy has an improved limit of resolution compared to electron microscopy' false.
