Now it's asking for it in nanometers, we'll worry about that later.

And when we divide all of these values out we get 1.7 times 10 to the negative 37.

Sorry, times 10 to the negative 32 meters.

1.7 times 10 to the negative 32 meters.

This is tiny, tiny, tiny,

too tiny to even observe kind of wavelength.

Let's go ahead and

convert it to nanometers cause that is what wavelength is usually reported at,

especially when we're dealing with electromagnetic radiation.

So a nanometer is 10 to the minus 9 meters and

that's going to give me 1.7 times 10 to the minus 23 nanometers.

So any particle, if you know its mass and

its speed, can have a calculated wavelength.

But it's only really the wavelength of the very,

very tiny, tiny particles that give you if you have a mass of very,

very small, very small mass.

Then you're going to have a wavelength that is actually measurable and

observable.
