Which is not the result of the special theory of relativity?

Correct answer: B. Space-time transformation

  • A. Length contraction
  • B. Space-time transformation
  • C. Time dilation
  • D. Mass variation

Explanation

Option B is not the result of the special theory of relativity. While space-time transformation is a concept that is used in the theory of relativity, it is not a direct result of the theory itself. The other options, length contraction, time dilation, and mass variation, are all consequences of the theory.

About Quantum Theory and Radiation

Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
