If a charged particle moves a magnetic field, when it exits the field, why is the magnitude of velocity the same? Is it because of there being no work acting on the particle?
I have ucat in around 6 days. After doing well in UCAT abstract reasoning for a while. I am suddenly struggling to figure out patterns. I don't know why this is the case.
When light passes through electrons I know that some light waves are absorbed excited state etc. Since, the absorbed light is released when electrons go back to ground state, what happens to the rest of the unabsorbed light? Does it just pass through the gaps between atoms?
