When to use DeBroglie Equation

Postby Mary Becerra 2D » Sun Nov 12, 2017 12:00 am

Do you only use this equation when finding wavelengths of objects with mass? Also, is it still valid when the said object is not in motion?

the equation is wavelength = planck's constant / mass x velocity. If there is 0 mass and/or velocity, the denominator would be zero and we cannot use the equation.

The DeBroglie Equation is used to find the wavelength of any particle with momentum! Hope this helps.

In the deBroglie equation, we have a constant (Planck's) and momentum. So we would use the equation when we know the mass and velocity of a particle.

This equation works for particles with momentum, and it has wave-like properties with wavelength.
