The image illustrates the absorption of different wavelengths of light by certain gases in Earth's atmosphere. Longer black arrows indicate less absorption. 100 km 10 km Sea level Gamma ray Opaque: ozone and O₂ block short-wavelength light H₂ (hydrogen) Absorbs ultraviolet light X-ray O₂ (oxygen) Ultraviolet H₂O (water vapor) Visible Infrared Visible window Using the image, categorize the gas molecules according to the wavelengths of light they absorb. Not all molecules will be used. Absorbs visible light Answer Bank Microwave CO₂ (carbon dioxide) Opaque: water and CO₂ block infrared light Radio O₂ (ozone) Radio window Absorbs infrared light CO (carbon monoxide)
When X-rays of wavelength 0.337 nm are directed at a crystalline sample, the smallest Bragg angle for a certain family of reflecting planes is found to be 10.5°. Within the sample, the atoms lie on a simple cubic lattice, a two-dimensional view of which is shown in the image. Assuming that the constructive interference observed is due to the pair of diagonal planes indicated by the two dashed lines, find the distance a between neighboring atoms. a = TOOLS x10' nm
