# De Broglie Wavelength Calculator

Wavelength is the distance between one peak of a wave to its corresponding another peak which has same phase of oscillation. It is represented by λ. The wavelength of a wave traveling at constant speed is given by λ = v/ f. In 1923, Louis De Broglie found that objects exhibit a wave nature and derived De Broglie equation to find 'λ' considering Plank's constant and Momentum (mv). Use this De Broglie Wavelength Calculator to find the wavelength of a particle.

#### De Broglie Equation:

l = h / p
m=h/(l×v)
v=h/(m×l)
**Where,**
l=Wavelength
h = Planck's Constant equal to 6.62607004 x 10^{-34}
p = Momentum of Particle (equal to m*v)
m=Mass
v=Velocity
### Example

Calculate the Wavelength of a particle having mass of 50 kg and velocity 20 m/s using De Broglie Wave Equation ?

#### Solution

= ( 6.62607004 x 10^{-34} ) / ( 1000)

= 6.62607004 x e^{-37}
