Electron Electron microscope Microscope Resolution Voltage

Click For Summary

To calculate the smallest distance that an electron microscope operating at 50 kV can resolve, one must first determine the de Broglie wavelength of electrons at this energy level. The de Broglie wavelength can be calculated using the formula λ = h / p, where h is Planck's constant and p is the momentum of the electrons. At 50 kV, the electrons have a specific momentum that can be derived from their kinetic energy. The resolution limit of the microscope is approximately equal to the de Broglie wavelength, allowing for the calculation of the smallest resolvable distance. Understanding these principles is essential for optimizing electron microscope performance.

ok! thanks!

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
