What you receive
- De Broglie wavelength in m from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
Momentum is approximated by mv, so speed should remain well below the speed of light.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
