ANSWER

[tex]1.02\cdot10^{16}Hz[/tex]

EXPLANATION

We want to find the frequency of UV light.

To do that apply the formula:

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

where λ = wavelength; f = frequency

Therefore, we have that:

[tex]\begin{gathered} 3\cdot10^8=2.94\cdot10^{-8}\cdot f \\ \Rightarrow f=\frac{3\cdot10^8}{2.94\cdot10^{-8}} \\ f=1.02\cdot10^{8-(-8)}=1.02\cdot10^{8+8} \\ f=1.02\cdot10^{16}Hz \end{gathered}[/tex]

That is its frequency.
