Which of the following represents de Broglie equation?

Options

  1. A= h mv
  2. B= h mv
  3. C= h mp
  4. D= p

Correct answer

B. = h mv

Step-by-step solution

According to de Broglie's hypothesis, every moving particle is associated with a wave. The wavelength of the matter wave is inversely proportional to the momentum p of the particle. = h p Since momentum p = mv , where m is the mass and v is the velocity of the particle, the equation can be written as: = h mv Answer: = h mv
