1. The problem statement, all variables and given/known data "If the photon has a short wavelength, and therefore a large momentum, the position can be measured accurately. But the photon will be scattered in a random direction, transferring a large and uncertain amount of momentum to the electron" 2. Relevant equations I am unsure about this formula: [Uncertainty in the measurement ~ Wavelength of photon] 3. The attempt at a solution How is this so? Is it because the electron can be anywhere along the wave before it scatters the wave? Therefore inducing the uncertainty? Thanks in advance.
