Figure E.1図 E.1
The plot shows the extent of light absorption versus wavelength for water. Absorption is reported in reciprocal meters and corresponds to the inverse of the distance light may travel through water before its intensity is diminished by 1/e (~37%).
英語のヒント
このグラフは、水による光の吸収の程度を波長に対して示す。吸収はメートルの逆数で表され、光の強度が1/e(約37%)だけ減少するまでに水中を進める距離の逆数に対応する。
