Answer:

The frequency of this light is 6.98\times 10^{14} s^{-1}.

Explanation:

Wavelength of the light = \lambda = 430 nm=4.30\times 10^{-7} m

Speed of the light = c = = 3\times 10^8 m/s

Frequency of the light = \nu

\nu =\frac{c}{\lambda }

\nu =\frac{3\times 10^8 m/s}{4.30\times 10^{-7} m}=6.98\times 10^{14} s^{-1}

The frequency of this light is 6.98\times 10^{14} s^{-1}.
