1. The problem statement, all variables and given/known data

The speed of light is 3 x $$10^8$$ m/s. Blue light has a wavelength of about 450nm (nm = 10^-9 m). Calculate the frequency of this light

2. Relevant equations

v=f$$\lambda$$

3. The attempt at a solution

3 x $$10^8$$ = f x 450
f = $$\frac{3 times 10^8}{450}$$

nearly there. Convert that wavelength to meters.
