- A photon, let's call it photon A, has twice the energy of a
photon B ¾The momentum of the photon A is greater than, equal to,
or less than photon B? ¾The wavelength of photon A is greater,
equal to or less than photon B? Fundamentally quantitavimante his
answer.
- The smallest distance (resolving power) of an electron
microscope is equal to the Broglie wavelength of the electrons it
emits. If the electrons start from rest, which it must be the
kinetic energy that must be printed to have the same resolving
power of a microscope using gamma rays of a frequency of 2.4 × 1019
Hz.?
Speed of light : c = 3 × 10^8[m/s]
Planck constant: h = 6, 626 × 10^(−34) [J· s]
Electron mass Me = 9, 1 × 10^(−31) [kg]
