One Method of Estimating the Thickness of the Ozone Layer

question 84

Multiple Choice

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 = 0.43 , is measured as 1.17. Approximate the thickness of the ozone layer to the nearest 0.01 centimeter.

• A)x = 2.72 cm
• B)x = 3.09 cm
• C)x = 0.24 cm
• D)x = 0.37 cm
• E)x = 0.07 cm
