- Amplitude: The strength of the electric field.
- Wavelength: The distance between maximum electric field locations.
- Frequency: The number of oscillations per second completed by the source charge.

- Wave Interference: When two or more waves combine to create a larger or smaller wave.
- Intensity: The power delivered by a wave per unit of area.
- Radiation Pressure: The force per unit area delivered by an electromagnetic wave.
- Electromagnetic Spectrum: The range of frequencies and wavelengths that encompass electromagnetic waves.
- Infrared Light: Wavelengths of light longer than red light.
- Ultraviolet Light: Wavelengths of light shorter than violet light.
- Photoreceptors: Light sensing cells in the retina of human eyes.
- True Color: The color of an object when illuminated by white light.
- Retinex: A collection of photoreceptors in the retina.
- Color Constancy: The ability of the eye to perceive true colors under a variety of lighting.
- Wien's Law: An experimental relationship between temperature of an object and the wavelength of light it emits.
- Ultraviolet Catastrophe: The failure of the electromagnetic wave model to recreate Wien's Law.
- Quanta: The smallest bit of energy possible in Planck's Hypothesis.
- Quantized Energy: The idea that all energy must be a multiple of a fundamental value.
- Energy State: A way to describe the value of the energy associated with a particular object.
- Quantum Number: A number that is used to multiply the quanta to obtain the energy state.
- Photoelectrons: Electrons ejected from surfaces when light shines upon them.
- Photoelectric Effect: The relationship between the wavelength of light and the appearance of photoelectrons.
- Electromagnetic Radiation: Waves of electric and magnetic fields that propagate through space.
- Photon: The smallest unit of an electromagnetic wave in the particle model of light.
- Gain Medium: The part of a laser that produces the laser light.
- Metastable State: A condition where excited electrons remain in an excited state for some period of time.
- Population Inversion: When there are more electrons in an excited state than in lower energy states.
- Laser Pumping: The process of transferring energy from the power supply to the gain medium.
- Optical Resonator: A component of a laser that traps and amplifies electromagnetic radiation before it is released as a beam.
- Particle-WAve Duality: The concept that objects display both wave-like and particle-like properties.
- Quantum Mechanics: The branch of physics that studies the behavior of particles on the atomic and subatomic level.
