Find the energy in kJ for a photon with a frequency of 3.12 x 1016 Hz. Warm Up Find the energy in kJ for a photon with a frequency of 3.12 x 1016 Hz.

Warm Up E = (6.63 x 10-34 j▪s)(3.12 x 1016 Hz) E=2.07 x 10-17 kJ x 1000 Joules = 2.07 x 10-14J 1 kJ

Atomic Spectra https://www.youtube.com/watch?v=lJh2Ra1eygA

Atomic Spectra Electrons jump from ground state to excited state when they absorb energy. Electrons emit light when they lose energy and return to lower energy levels (ground state).

Atomic Spectra Light emitted by atoms consists of a mixture of specific frequency. Each frequency corresponds to a particular color. When passing through a prism light separates (based on frequency) into discrete lines (atomic emission spectrum).

Quantum Mechanics (vs Classical) Photons = light quanta DeBroglie: All moving objects have wavelike behavior (however you cannot observe a wavelength unless the mass of the object is incredibly small) Heisenberg Uncertainty Principle: It is impossible to know exactly both the velocity and the position of a particle at the same time. (only matters for very small objects) https://www.youtube.com/watch?v=2yCgXu5rQok
