Question

Fill in the blanks, virus can only be seen only through a _microscope.​

Answer 1

Explanation:

Because the wavelengths of visible light range from roughly 300 to 800 nanometers, viruses aren't exactly visible under normal lighting. Only optical fluoresce microscopes can see inside a virus, and then only indirectly, using dye, which cannot actually penetrate a virus

Answer 2

Answer:

electron microscope

Explanation:

Viruses are so small they can only be seen under an electron microscope (EM) as quite undefined grainy images.

extra information :- Unlike other unicellular organisms like bacteria, viruses are commonly referred to as particles rather than cells. ... Their size also makes a majority of viruses impossible to see under a light microscope. * A virus is between 100 and 500 times smaller than bacteria.
