unit of wavelength

[Quynh Vo]

What is the unit for wavelength in the de broglie equation? Is it meters or nanometers or other?

[Mariepahos4D]

The De Brogile wavelength unit is meters, but you would often convert to nm at the end to get correct sig figs

[Marty Hockey]

The unit is in meters but is often extremely small so it is expressed in nanometers. For example, you would be given a wavelength of 1.5 x 10^-9 meters which could otherwise be written as 1.5 nm.

when you work with the equation, you use meters, but often you convert the final answer into nanometers because it is more visually appealing this way.

[Caitlin Ciardelli 3E]

according to SI units, you measure wavelength in meters (m) since it is technically a distance! However, a lot of the wavelengths we find are much smaller than this so sometimes it is easier to keep track of using other units such as nm. (# x 10^-9 m)

The unit is most likely in meters.
