When to use DeBroglie Equation

[Mary Becerra 2D]

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?

[Christina Cen 2J]

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.

[Carlos Gonzales 1H]

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.
