Wavelength and De Broglie Equation

Postby Maria Roman 1A » Fri Apr 20, 2018 4:49 pm

Is calculating wavelength and calculating the De Broglie wavelength the same thing?

Yes, technically both are determining wave length. The De Broglie wavelength just relates wavelength to speed.

It's important to remember though that De Broglie can only be used with particles because they have mass, so it's not applicable to light.

Not necessarily because De Broglie cannot be used for light but it can be used for things with mass.

De Broglie's equation only applies to objects with mass. So, it does not apply to light because photons don't have a mass.

Both formulas are calculating wavelength, but De Broglie's equation only applies to certain things, specifically objects with mass, so not to light, because light doesn't have mass. The wavelength equation, on the other hand, can calculate the wavelength of both objects with mass and of light.

Avoid using De Broglie when it comes to light, only when mass comes up.

If this equation doesn't relate to light then what wavelength is it calculating?

The De Broglie equation is just another way of calculating wavelength, but there are also other ways.

Well, yes however you would use the De Broglie equation when its referring to mass as well.
