Numerical Problems

Remarks

  1. Be careful about tensor indices. Practice problems from Spiegel and Arfken-Weber Book.
  2. When solving assignments, try to draw a neat & physical diagram of events and explain the symbols. Read the question carefully and after solving the problem, frame and write a clear sentence of answer that is asked in the question.
  3. Video-lecture on Orthogonal Transformation.
  4. Video-lecture on Proper Homogeneous Lorentz Group.

Topics

  1. Michelson-Morley Experiment and its outcome: Postulates of Special Theory of Relativity. Lorentz Transformations. Simultaneity and order of events. Lorentz contraction. Time dilation. Relativistic transformation of velocity. Relativistic Dynamics. Variation of mass with velocity. Massless Particles. Mass-energy Equivalence. Transformation of Energy and Momentum.
  2. A Short Introduction to Tensors: Covariant and contravariant vectors. Contraction. Covariant, contravariant, and mixed tensors of rank-2, transformation properties. The metric tensor (flat space-time only). Raising and lowering of indices with metric tensors. (Consistent use of convention → diag(1,-1,-1,-1).)
