SUMMARY
The discussion clarifies that electron microscopes are preferred over visible light microscopes due to the diffraction limitations of light. Photons, which have no mass and are often misunderstood in terms of size, have a wavelength of approximately 500nm, causing significant blurring in imaging small objects. In contrast, electrons exhibit wave-like behavior with much smaller wavelengths, resulting in reduced diffraction and clearer images. The conversation emphasizes the importance of using the wave model of light for better understanding rather than focusing on the concept of photon size.
