Quantum electrodynamics is the study of energy exchange among these two elementary particles
photons and electrons
200
This is the bending of light as it passes through matter
refraction
200
The distance from one peak to the next, or from one trough to the next, or across three nodes separated by one peak and one trough, is this
wavelength
200
The variable "lambda" represents this wave property
wavelength

This "braking radiation" is produced when electron trajectories are slowed due to nuclear attraction
bremsstrahlung
300
This is the bending of light around matter
diffraction
300
This is the time required for a wave to propagate a distance of one wavelength
period
300
The amount of energy borne by a photon of light can be calculated by this equation
E = hv
300
