What is Meant by De Broglie Wavelength?

In Physics, the De Broglie wavelength is defined as the wavelength in which the object is associated with its mass and momentum. It is noted that the object force and the De Broglie wavelength are inversely proportional to each other. This equation shows a relationship between wave nature and particle nature of a body. Mathematically, de Broglie wavelength formula can be denoted as:

λ = h/p (or) λ = h/mv

Where, 

λ is the wavelength

p is the momentum of the photon

h is the Planck’s constant = 6.626 × 10 −34 J−s
