The wavelength of a matter wave is independent of:
Correct answer: D. Charge
- A. Mass
- B. Velocity
- C. Kinetic energy
- D. Charge
Explanation
The wavelength of a matter wave is indeed independent of charge. The de Broglie wavelength is applicable to all particles, whether they are charged or neutral. Charge does not directly influence the wavelength of matter waves, so it is correct to say that the wavelength is independent of charge.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
