DeBroglie Equation

Postby AMahadi » Sun Oct 13, 2019 10:51 am

Why can't the DeBroglie Equation be applied to light?

Because light has no mass

This is because DeBroglie equation refers to moving particles such as a car or an electron. However, light is electromagnetic radiation and therefore you could only apply the electromagnetic equations λv=c and E=hv to photons.

Light does not have mass, so the DeBroglie equation would not work.

Since you have to have a mass to find wavelength using DeBroglie's equation, it would be impossible for it to work for light because light has no mass.

Considering the DeBroglie equation, which needs you to calculate the momentum=mv, the light does not have a mass, so you can't use this equation for light.

The DeBroglie Equation can not be applied to light because light has no mass.

When using the DeBroglie equation, do the units for mass have to be in grams, and does the velocity have to be in meters per second?

So, De Broglie's equation can only be applied to things that have a mass and velocity (p)?

The DeBroglie Equation is only used for any moving particles with momentum and has wavelike properties with wavelength. Light does not have any mass so it cannot be used to calculate momentum.
