The robotic probe had avariety of instruments, including adevice that used ground-penetrating radar and a spectral photometer (SPM), that were used to investigate the planet Mars. Ground-penetrating radar can be used to examine subsurface structures and search for evidence of specific rock formations that would indicate the previous presence of water. This device has an antenna that has a length of 1.00 m, which is half the wavelength of the radar's electromagnetic radiation (EMR). An SPM can be used to identify the presence of particular substances. The SPM emits EMR over a broad range of the electromagnetic spectrum and detects those wavelengths that are reflected from the sample being examined. The photons that are not reflected cause electron transitions within the sample. The graph below shows SPM data for a particular sample and the deep dip, labelled CO2, indicates that carbon dioxide is present. Percentage of EMR Reflected as aFunction of Wavelength
Percentage of EMR Reflected as a Function of Wavelength 100 95 Percentage reflected 90 85 co 2 10 15 Wavelength (10-6 m)Numerical Response 2. The difference in the energy levels of a CO, molecule associated with the deep dip in the SPM data, expressed in units of electron volts and in scientific notation, is a.be x 10 deV. The values of a, b, c, and d are and (Record all four digits of your answer in the numerical-response section on the answer sheet.)Step by Step Solution
