First Semester (Computer Science) examination paper for Applied Physics (BCS-103) from November 2019. It includes questions on interference conditions, specific rotation, special theory of relativity, Norton and Thevenin's theorems, double refraction, Helium-Neon gas laser, Michelson-Morley experiment, and resolving power of optical instruments."}

Questions:

  1. Write any four conditions to obtain well-defined interference.
  2. Define specific rotation.
  3. What are the postulates of special theory of relativity?
  4. Write the expressions for average value and RMS value of a half-wave rectified sinusoidal voltage.
  5. State Norton's theorem.
  6. Explain the phenomenon of double refraction in calcite or quartz.
  7. Define length contraction and derive the formula for it.
  8. Explain the concept of a phasor. How is it different from a vector?
  9. Describe the construction of a Nicol's prism. Explain how it can be used as a polarizer and as an analyzer.
  10. With necessary theory and energy level diagram, explain the working of a Helium-Neon gas laser.
  11. Describe the Michelson-Morley experiment and discuss its negative result.
  12. State and prove Thevenin's theorem.
  13. What is meant by the resolving power of an optical instrument? Explain Rayleigh's criterion for just resolution.
