Review Questions

• How did Albert Einstein's theory of relativity change our understanding of terrestrial radiation?
  • Einstein's theory of relativity revolutionized our understanding by providing insights into how energy behaves in relation to mass and gravity. This understanding is crucial when examining terrestrial radiation since it involves energy emitted from the Earth's surface. The principles outlined in relativity help us understand the absorption and emission processes involved in terrestrial radiation, ultimately affecting climate models and energy balance calculations.
• In what ways did Einstein’s explanation of the photoelectric effect contribute to the field of light scattering?
  • Einstein's explanation of the photoelectric effect highlighted that light behaves as both a wave and a particle, leading to a better understanding of how light interacts with matter. This dual nature is essential for understanding scattering phenomena. When light scatters, its particle-like behavior can cause changes in its wavelength and intensity based on interactions with particles in various mediums, which is a key principle used to analyze atmospheric conditions.
• Evaluate the impact of Einstein’s contributions on modern physics, particularly in relation to our understanding of atmospheric phenomena.
  • Einstein's contributions significantly advanced modern physics by reshaping theories surrounding energy, mass, and light.
