Quantum Mechanics - Day 2

Front

Photoelectric effect

Back

The photoelectric effect is the emission of electrons from a material when it is exposed to light of sufficient frequency.

Einstein discovered this by advancing Planck's theory.

Modern view of light's nature

Back

Dual nature: wave-particle duality

Front

Continuous spectrum

Back

A spectrum that shows all colors without interruption.

Front

Light source

Back

Provides the initial light for the spectrum experiment.

Front

Energy level n=5

Back

Furthest from the nucleus.

Front

Relationship between energy level and energy

Back

Higher n means higher energy.

Front

Limitation of the energy formula.

Back

The equation does not account for the electrostatic forces between multiple electrons.

Front

White Light Source

Back

Emits all wavelengths, creating a continuous spectrum.

Front

Emission Spectra

Back

The unique pattern of light emitted by an element; elements in the gas phase emit light when exposed to heat or electricity.
