Explores electromagnetic wave propagation, including Poynting vector, irradiance, dipole radiation, dielectric constant, and natural linewidth in atoms and radiation.
Explores the photon concept in electromagnetic waves, including energy, momentum, emission by charges, coherence length, and the electromagnetic spectrum.
Explores electromagnetic radiation interaction with matter, covering absorption, diffusion, reflection, and refraction, with practical examples like the color of the sky and moon darkness.
Explores atoms and radiation lineshapes, covering linewidths, lifetime broadening, and broadening mechanisms, including Lorentzian and Doppler effects.
Explores beam-matter interactions, focusing on emission phenomena from core electron ionization by X-Rays and electrons, and the competition between Auger and X-Rays emissions.
Explores the origin of radionuclides from supernova explosions and their role in nature, covering topics such as nuclear astrophysics, cosmic element formation, and stellar evolution.
