Question

What is the frequency of ultraviolet light with wavelength 2.94 x 10^-8 m? (c= 3.00 x 10^8 m/s)

Answer 1

`1.02\cdot10^(16)Hz`

Step-by-step explanation

We want to find the frequency of UV light.

To do that apply the formula:

`c=\lambda f`

where λ = wavelength; f = frequency

Therefore, we have that:

`\begin{gathered} 3\cdot10^8=2.94\cdot10^(-8)\cdot f \\ \Rightarrow f=(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}`

That is its frequency.
