Which of the following shows Planck's quantum theory
Correct answer: D. None of these
- A. E= hcv
- B. E= c/v
- C. E= cv
- D. None of these
Explanation
Planck's quantum theory is fundamentally characterized by the equation E = hv, where E is the energy of a photon, h is Planck's constant, and v is the frequency of the electromagnetic wave. The other options provided do not reflect this relationship accurately:Option A: E= hcv - This option incorrectly includes both the speed of light (c) and a frequency (v) in a manner that does not adhere to Planck's equation.Option B: E= c/v - This suggests an inverse relationship between energy and frequency, which is contrary to the principles of quantum mechanics.Option C: E= cv - This option omits the essential Planck's constant (h), making it an incorrect representation of energy in quantum theory.Therefore, the correct response is Option D: None of these, as none of the given equations accurately express Planck's quantum theory.

About Planck's Quantum Theory
Planck's quantum theory states that energy is emitted or absorbed in discrete packets called quanta, with each packet having energy E = hν. It covers the meaning of Planck's constant, the relationship between frequency and wavelength, and how quantisation differs from the classical continuous model of energy.
