## Homework Statement

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

## Homework Equations

v=f[tex]\lambda[/tex]

## The Attempt at a Solution

3 x [tex]10^8[/tex] = f x 450

f = [tex]\frac{3 times 10^8}{450}[/tex]
