Read the following statements carefully: (I) The Compton effect and photoelectric effect demonstrate the wave nature of light. (II) The de Broglie wavelength of a moving particle is independent of its charge for a given momentum. (III) Interference and diffraction strongly support the wave theory of light. (IV) The energy of a photon is directly proportional to its frequency and inversely proportional to its waveleng

B. 3

Step-by-step solution

Statement (I) is incorrect because the Compton effect and photoelectric effect can only be explained by the particle nature of light. Statement (II) is correct. The de Broglie wavelength is given by = h p . For a given momentum p , it depends only on Planck's constant h and is independent of the particle's charge. Statement (III) is correct. Phenomena like interference and diffraction are classical wave phenomena that strongly support the wave theory of light. Statement (IV) is correct. The energy of a photon is gi
