### Measurable V. Non-Measurable

What wavelength values from De Broglie's equation indicate whether or not a particle or electron has detectable wavelength properties?

If the De Broglie wavelength value is greater than 10^-15, it is measurable.

Any de Broglie wavelength less than 10–15 is typically not going to have experimentally detectable wavelike properties, making it more particle-like.

A particle with a De Broglie wavelength less than 10^-15m does not have detectable wave-like properties.

In his example in class, how come it was not measurable if it was 10^-38?

^ Because 10^-38 is a smaller value than 10^-15, therefore it is not measurable.
