# Frequency of light

## Homework Statement

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

## Homework Equations

v=f$$\lambda$$

## The Attempt at a Solution

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