Answer:
frequency of light = [tex]4.2\times 10^{-13}[/tex]
Explanation:
we know that relation between frequency and wavelength of light is
frequency × wavelength = speed of light.
therefore frequency = [tex]\frac{c}{wavelength}[/tex]
= [tex]\frac{3\times 10^{8}}{6.98\times 10^{-6}}[/tex]
=[tex]4.2\times 10^{-13}[/tex]
