### When to use DeBroglie Equation

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.
