Answer:
5.46 x 10¹⁴ Hz
Explanation:
The relation between frecuency (ν) and wavelength (λ) is given by:
c = λν
Where c is the speed of light and it is constant: 2.998 x 10⁸ m/s.
Given: λ = 549 nm x 10⁻⁹ m/1 nm = 5.49 x 10⁻⁷ m
We calculate the frequency of the light as follows:
ν = c/λ = (2.998 x 10⁸ m/s)/(5.49 x 10⁻⁷ m) = 5.46 x 10¹⁴ s⁻¹ = 5.46 x 10¹⁴ Hz
