The image above represents velocity. To calculate velocity, three essential parameters are needed and these parameters are Planck’s Constant (h), Wavelength (λ) and Mass (m).
The formula for calculating velocity:
v = h / λm
Where;
v = velocity
λ = wavelength
h = Planck’s constant
m = mass
Let’s solve an example;
Find the velocity when the wavelength is 10, the planck’s constant is 6.626e-34 and the mass is 5.
This implies that;
λ = wavelength = 10
h = Planck’s constant = 6.626e-34
m = mass = 5
v = h / λm
So, v = 6.62607004e-34 ⁄ (10)(5)
v = 6.62607004e-34 ⁄ (50)
v = 1.33e-35
Therefore, the velocity is 1.33e-35 m/s.
