Speed of light in a vacuum is same for all observers. The uncertainty principle states that a. A particle's displacement cannot be precisely defined or measured. A particle's energy cannot be precisely defined or measured. The product of a particle's displacement times its momentum cannot be precisely defined or measured.
Students are always uncertain of the professor's intentions.
According to the de Broglie hypothesis, the wavelength of a moving particle is a. directly proportional to its energy b. directly proportional to its momentum c. inversely proportional to its energy d. The exclusion principle prevents a. two electrons from occupying the same quantum state. The half-life of a radioactive element refers to a. half of the lifetime of individual atoms. The decay constant of the material. The time interval in which half of the atoms in a sample will decay.
