## Homework Statement

Show that for a nonrelativistic particle, a small change in speed leads to a change in de Broglie wavelength given from

## The Attempt at a Solution

I have tried to expand the left hand side of the equation, but found that it gave the answer of v0/delta v. My definition of delta lambda is the final wavelength minus the initial wavelength.
