The frequency of the absorption is #5.69×10^14 color(white)(l)"s"^"-1"#.

Explanation:

The formula relating frequency and wavelength is

#color(blue)(|bar(ul(fλ=c)|)#

where #f# is the frequency, #λ# is the wavelength, and #c# is the speed of light.

We can rearrange the formula to get

#f = c/λ = (2.998×10^8 color(red)(cancel(color(black)("m")))"·s"^"-1")/(527×10^"-9" color(red)(cancel(color(black)("m")))) = 5.69 × 10^14color(white)(l) "s"^"-1"#
