If alpha, beta and gamma rays carry same momentum, which has the longest wavelength?

Options

  1. AAlpha rays
  2. BBeta rays
  3. CGamma rays
  4. DNone, all have same wavelength

Correct answer

D. None, all have same wavelength

Step-by-step solution

On the basis of dual nature of light, Lious de-Broglie suggested that the dual nature is not only of light, but each moving material particle has the dual nature. He assumed a wave to be associated with each moving material particle which is called the matter wave. The wavelength of this wave is determined by the momentum of the particle. If p is the momentum of the particle, the wavelength of the wave associated with it is = h p where h is Planck's constant. Since, it is given that, alpha, beta and gamma rays carr
