# De Broglie Wavelength Problem

## Homework Statement

What is each of the following?
(a) the wavelength of a 6.0 eV photon
m
(b) the de Broglie wavelength of a 6.0 eV electron
m

?

## The Attempt at a Solution

None so far

$$\lambda=\frac{h}{mv}$$

nevermind use this formula

$$f = \frac{E}{h}$$

and $$c = \lambda f$$

by th way this is probably in your textbook or in your notes...

you can also look this up on wikipedia, for example

I've already solved part a. The De Broglie wavelength is given by the equation $$lambda=h/p$$.
