Did you know?
WebFrom quantum physics, electrons should not be able to pass through given barriers (such as air). However, when they are able to pass through such barriers, the electrons produce what is refered to as a tunneling current. … WebNo, we can't see an electron. We see things when light is either emitted from them (like the sun or a lightbulb) or when light bounces off of them (any of the objects in your room). An electron shouldn't be pictured as a really really tiny grain of sand, which is what you are tempted to think when you learn about the Bohr atom and electrons ...

WebJan 29, 2024 · If you give electrons the same wavelength range, you get energies of about $2.7\times 10^{-6} \operatorname{eV}$ to $1.0 \times 10^{-5}\operatorname{eV}$. Electrons of that energy would not be able to trigger the changes in the light sensitive proteins, let alone penetrate the eyes to get to the photo-receptors.
