One Method of Estimating the Thickness of the Ozone Layer

One method of estimating the thickness of the ozone layer is to use the formula , where I _o is the intensity of a particular wavelength of light from the sun before it reaches the atmosphere, I is the intensity of the same wavelength after passing through a layer of ozone x centimeters thick, and k is the absorption constant of ozone for that wavelength. Suppose a wavelength of cm with k = 0.45 , is measured as 1.14. Approximate the thickness of the ozone layer to the nearest 0.01 centimeter.

A) x = 0.06 cm
B) x = 2.82 cm
C) x = 0.16 cm
D) x = 2.53 cm
E) x = 0.29 cm
