The smallest particle that can be seen with a light microscope is about 0. 2 microns. If an object is smaller than that, the light's wavelength cannot traverse it causing it to fall out of the visible spectrum.

The smallest particle visible under a light microscope is typically around 200 nanometers in size. This includes small microorganisms like bacteria or large viruses. Particles smaller than this require electron microscopes for visualization.
An electron microscope uses a beam of electrons to achieve higher resolution and magnification compared to a light microscope, which uses visible light. Electron microscopes can visualize objects at the nanoscale level, while light microscopes are limited to the micrometer range.
The smallest object that can be resolved in a light microscope is typically around 200 nanometers, which is close to the wavelength of visible light used in these microscopes. This limit is known as the diffraction limit.
Viruses are too small to be seen with a light microscope because they are smaller than the wavelength of visible light. This means that light cannot pass through them or be reflected off of them, making them invisible under a light microscope.
A compound microscope typically uses light energy, specifically visible light, to illuminate the sample being observed. This light passes through the lenses of the microscope to magnify and visualize the specimen.
Blue light has the smallest wavelength in the visible spectrum.
