Quizplus · Accepted Answer

According to the Heisenberg Uncertainty Principle, the more precisely the position of a particle is known, the less precisely its momentum can be known, and vice versa. This principle implies that if the wavelength (related to momentum) of a photon is known very precisely, its location cannot be determined with high precision. Energy, momentum, and frequency of a photon can all be precisely determined if the wavelength is known, as they are directly related through physical equations.
