NEET Chemistry (general) MCQ Question
Which of the following statements about the de Broglie wavelength and energy of photons is correct?
The de Broglie wavelength increases with increasing momentum.
The energy of a photon is directly proportional to its wavelength.
A photon emitted during a transition from a higher to a lower energy level has a frequency that can be calculated using E = hν.
The de Broglie wavelength of a particle is independent of its velocity.
Correct Answer
Detailed Explanation
Statement C is correct as it aligns with the principle that the energy of a photon emitted during electronic transitions can be expressed using the equation E = hν, where ν is the frequency. Statement A is incorrect since the de Broglie wavelength decreases with increasing momentum, while statement B is misleading as energy is inversely proportional to wavelength. Statement D is incorrect since the de Broglie wavelength is dependent on velocity.
