Please please tell me exact and accurate answer i have only one chance left please tell me right answr.. will rate thanks!!

can someone label where a spectral window/infrared window would be/look like on a IR spectrum?

Please try to give type solution fast i will rate for sure

pls help!

state if true or false 1. Prior to a fixed point or wavelength reading, spectral scanning can be done to determine the maximum absorbance wavelength of a sample. 2. The purpose of a diffraction grating is the same as that of a prism. 3. In any UV-VIS spectrophotometer, the light is filtered first to a single wavelength or narrow range before it hits the sample 4. In any UV-VIS spectrophotometer setup, the detector always comes right after the sample container. 5. It is necessary to set the blank before each reading even if the only difference between the sample solutions is the amount of analyte. 6. Prior to a fixed point/wavelength reading, spectral scanning can be done to determine the maximum absorbance wavelength of a sample.

Review | Constants | Periodic Table An astrophysicist working at an observatory is interested in finding clouds of hydrogen in the galaxy. Usually, hydrogen is detected by looking for the Balmer series of spectral lines in the visible spectrum. Unfortunately, the instrument that detects hydrogen emission spectra | only Part A detects spectra in the infrared region of electromagnetic radiation. Therefore, the astrophysicist decides to check for hydrogen by looking at the Paschen series, which produces spectral lines in the infrared part of the spectrum. The Paschen series describes the wavelengths of light emitted by the decay of electrons from higher orbits to the n = 3 level. at this particular observatory is not working very well and What wavelength A should the astrophysicist look for to detect a transition of an electron from the n = 7 to the n = 3 level?

If the 310 nm radiation provides exactly the energy to break an average chemical bond in the skin, estimate the average energy of these bonds in kJ/mol. Express…

Why is  λ max significant?    The instrument response is highest at that wavelength.   The value can indicate the observed color of solution.   The value indicates the amount of light absorbed   The value is can be used to identify a particular chemical.   The value increases as the energy of light increases.
