[tex]\lambda=\frac{h}{mv} [/tex]

what about the velocity?
nevermind use this formula

[tex] f = \frac{E}{h} [/tex]

and [tex] c = \lambda f [/tex]

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 [tex] lambda=h/p [/tex].
