An inertial frame of reference is one which satisfies:

Correct answer: A. Newton's theory

  • A. Newton's theory
  • B. Einstein's theory
  • C. Hertz theory
  • D. Special theory of relativity

Explanation

An inertial frame of reference is one that satisfies the following conditions: It is not accelerating. It is not rotating. It is not experiencing any external forces. In an inertial frame of reference, Newton's laws of motion hold true. This means that if an object is at rest in an inertial frame of reference, it will remain at rest unless acted upon by a force. Similarly, if an object is moving at a constant velocity in an inertial frame of reference, it will continue to move at that velocity unless acted upon by a force.

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.
