One theory is that amoebas are really, really tiny, and that the human eye is unable to magnify the recieved images to see them.
Other theories state that amoebas don't exist, are invivisible and have poor comunication skills.
Electromagnetic radiation having a wavelengths between 380 - 750nm is visible to the normal human eye. This region of the spectrum is called visible light. Radiation of any other wavelength cannot be seen with the naked eye
microscope
It enables you to zoom in on things that you cannot see with the naked eye
Something that is visible to the naked eye, really!
Magnification is important in science because it allows for the direct observation of processes that are invisible to the naked eye.
No, amoebas are not visible to the naked eye as they are microscopic organisms.
No, the human egg is not visible to the naked eye as it is microscopic in size.
No, human eggs are not visible to the naked eye as they are microscopic in size.
No, the human egg cell is not visible to the naked eye as it is microscopic in size.

Amoebas are unicellular organisms. That is, they are made of one single cell, and are invisible to the naked eye, without a microscope.
They are too small for the naked eye to see.
yes but we should have a sharped eye a common person people cant see this
Organisms that are so small they cannot be seen by the naked eye are called microorganisms. Examples include bacteria, viruses, fungi, and some types of single-celled protists like amoebas and paramecia. These microorganisms play important roles in various ecosystems and can have both positive and negative effects on human and environmental health.

Radio waves are too long for the human eye to see. The light that is visible to the human eye consists of a small portion of the electromagnetic spectrum. Radio waves have wavelengths longer than visible light, making them invisible to the naked eye.
