Microscope Theory - Alternatives to the use of visible light? Hey guys. I've been googling for ages but I've had no luck with this so I thought you guys could help me figure this out. Why can't UV light or gamma rays be used to observe objects in microscopy? I know the main idea behind the use of electron microscopes is that electrons can behave as waves with much smaller wavelengths than light can, thus allowing us to observe smaller objects. However, why can't UV light or Gamma Rays (X rays cannot be focused) be used instead of visible light or electrons to observe objects? They have a smaller wavelength than visible light and will therefore result in improved magnification. 2. Relevant equations N/A 3. The attempt at a solution I've checked my textbook but it fails to address gamma rays and UV light is only mentioned to be difficult to work with. Are gamma rays too hazardous to use? As for UV rays, I really have no idea why specifically they're difficult to use in this context. Thanks for reading, and I hope what I'm asking is relatively clear.
