Macroscopic Domain

Macroscopic domain includes phenomena at large scales like laboratory, terrestrial and astronomical. It includes following subjects:

• Mechanics – It is based on Newton’s laws on motion and the laws of gravitation. It is concerned with motion/equilibrium of particles, rigid and deformable bodies and general system of particles. Examples,
  • Propulsion of rocket by ejecting gases
  • Water/Sound waves
  • Equilibrium of bent rod under a load

• Electrodynamics – It deals with electric and magnetic phenomena associated with charged and magnetic bodies. Examples,
  • motion of a current-carrying conductor in a magnetic field
  • the response of a circuit to an ac voltage (signal)
  • the propagation of radio waves in the ionosphere

• Optics – It deals with phenomena involving light. Examples,
  • Reflection and refraction of light
  • Dispersion of light through a prism
  • Colour exhibited by thin films

• Thermodynamics – It deals with systems in macroscopic equilibrium and changes in internal energy, temperature, entropy etc. of systems under application of external force or heat. Examples,
  • Efficiency of heat engines
  • Direction of physical and chemical process
