Transmission Spectrum of an Earth-like Atmosphere

Graphic titled “Transmission Spectrum of an Earth-Like Atmosphere” includes a detailed line graph of light blocked on the vertical y-axis versus wavelength on the horizontal x-axis. A satellite image of Earth is included in the background.

Graph Axes

The y-axis, labeled “Light blocked,” has an arrow pointing upward. The bottom of the arrow is labeled “Less,” and the top of the arrow is labeled “More.” There are no numbers, units, or tick marks on the y-axis.

The x-axis, labeled “Wavelength (nanometers),” increases in wavelength from left to right, with evenly spaced tick marks at 5,000; 10,000; 15,000; and 20,000 nanometers. The origin at the far left is not labeled.

Graphed Data

The spectrum consists of data points connected by straight lines. The overall shape is irregular, with numerous peaks of various heights and widths, but no obvious systematic pattern. Some of the narrow peaks are superimposed on broader peaks. The baseline is flat. (There is no overall trend from the left to right side of the graph.)

Prominent peaks are labeled:
