Applying the DeBroglie Equation

Postby Vincent Leong 2B » Fri Oct 11, 2019 4:34 pm

When is the DeBroglie Equation applicable? More specifically, what type of particles or substances can we use the DeBroglie equation to solve a problem?

The De Broglie Equation is used for any particle with momentum and has wavelike properties with a wavelength. Remember to not use EM equations for electrons!

The De Broglie equation says that any moving particle with momentum p has wavelike properties with wavelength λ, so it's applicable for any moving particle.

The DeBroglie equation can't be applied to light

Ironically, the Debroglie equation was derived from equations using light, however the wavelength of light cannot be found using debroglie's equation due to the equation requiring mass.

The DeBroglie equation is used to find the wavelength of anything that has momentum (mass in motion). With the DeBroglie equation, we can tell if an object displays wave-like properties, depending on its mass.

The DeBroglie equation can be used on any particle with momentum, and is used to determine the wavelength of the particles movement. Since momentum is calculated by multiplying mass by velocity, the equation cannot be used for light particles as light does not have mass and thus does not have momentum.
