## Homework Statement

## Homework Equations

1/2 mv^2

E = hf

c = f (wavelength)

## The Attempt at a Solution

0.5 * (9.109 * 10^-31) * (6 * 10^4)^2 = energy

energy = hf => f = energy/(6.626*10^-34) = 2.47 * 10^12

wavelength (m) = (speed of light) / frequency

wavelength (m) * (1*10^9) = 121235.4

Answer is 12. What gives guys im 4 decimal places too high is there some unit for any of the equations im not getting?

Any help is greatly appreciated.
