First Semester (Computer Science) examination paper for Applied Physics (BCS-103) from December 2018. It includes questions on particle speed and rest energy, interference conditions, laser beam properties, time constants, meson velocity, Einstein's mass-energy relation, resolving power, polarized light, thin film interference, Einstein's coefficients, and relativity theory."}

Questions:

  1. The total energy of a particle is exactly twice its rest energy. Find its speed.
  2. State Thevenin's theorem.
  3. What is an interference of light?
  4. What are the characteristic properties of a laser beam?
  5. Show that the time for attaining half the value of the final equilibrium (maximum) current in a circuit having an inductance L and a resistance R in series is 0.69 L/R.
  6. What is the velocity of mesons whose proper mean life is 2.510 seconds and observed mean life is 2.510 seconds?
  7. State and prove superposition theorem.
  8. Deduce Einstein's mass-energy relation, E = mc.
  9. Write short notes on the resolving power of telescope.
  10. Write short notes on circularly and elliptically polarized light.
  11. Describe the phenomenon of interference in thin films. Find the conditions of maxima and minima. Show that these conditions are complementary in reflected and transmitted light.
  12. What are Einstein's coefficients? Describe the construction and working of Helium-Neon Laser.
  13. Describe the construction and working of a Nicol's Prism. Explain how it can be used as an analyzer.
