Question

What is De Broglie Hypothesis?


Open in App
Solution

  1. De Broglie's Hypothesis says that Matter consists of both the particle nature as well as wave nature.
  2. De Broglie wavelength λ is given as λ=hp, where p represents the particle momentum and can be written as:
    λ=hmv
    Where, h is the Planck's constant, m is the mass of the particle, and v is the velocity of the particle.
  3. From the above relation, it can be said that the wavelength of the matter is inversely proportional to the magnitude of the particle's linear momentum.
  4. This relation is applicable to both microscopic and macroscopic particles
  5. The de Broglie equation is one of the equations that is commonly used to define the wave properties of matter.
  6. Electromagnetic radiation exhibits the dual nature of a particle (having a momentum) and wave (expressed in frequency, and wavelength).
