Thickness of the ozone layer The thickness of the ozone layer can be estimated using the formula

where I0 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 θ is the acute angle that the sunlight makes with the vertical. Suppose that for a wave­length of 3055 × 10−8 centimeter with k ≈ 1.88, I0/I is measured as 1.72 and θ = 12°. Approximate the thickness of the ozone layer to the nearest 0.01 centimeter.
