question 51

Multiple Choice

The thickness of the ozone layer can be estimated using the formula where I ₀ 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, k is the absorption constant of ozone for that wavelength, and is the acute angle that the sunlight makes with the vertical. Suppose that for a wavelength of 3,055 10 ^{- 8} centimeter with k 1.93, I _o /I is measured as 1.72 and . Approximate the thickness of the ozone layer to the nearest 0.01 centimeter.
