Document Summary
Sc/biol 2010 first term test (4 february 2013) key page 1 of 5: b and c, ca 1,000 nm, ca 10,000,000 nm, ca 100 nm, ca 1,000,000 nm, ca 10,000 nm, none of the above. [01] wein"s displacement law defines the wavelength of maximal photon flux as a constant divided by temperature ( max = 3. 6 106 (nm k) / t ( k)). If the temperature of an incandescent lamp is 3600 k (its color temperature), what would be the approximate (ca) wavelength of maximal photon flux from the lamp: ca 10. 0 nm, ca 100,000 nm. Even without a calculator, you can obtain the correct answer by subtracting the powers of 10 (6-3=3) for 1,000 nm: c. [02] which of the following atmospheric gases absorb significant amounts of solar radiation (choose the best answer): co2 (carbon dioxide) c. co (carbon monoxide) d. ne (neon, n2 (nitrogen, ar (argon, a and b, b, c and e.
