One Method of Estimating the Thickness of the Ozone Layer

question 20

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 = 0.45 , 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

Definitions:

Summer

Summer is one of the four temperate seasons, characterized by warmer weather, longer days, and typically occurs between spring and autumn.

Temperate Lakes

Freshwater lakes found in regions with moderate climates, often characterized by distinct seasonal temperature variations.

Epilimnion

The upper layer of water in a stratified lake, characterized by warmer temperatures and high levels of dissolved oxygen.

Hypolimnion

The lower layer of water in a stratified lake, characterized by being cold and typically oxygen-deficient, lying below the thermocline and epilimnion.
