(a)
Interpretation:
The wavenumber at the following frequency and the frequency of the transducer is to be stated:
The velocity of the Michelson interferometer is
Concept introduction:
Frequency refers to the number of times or number of the occurrences of a particular event in a unit of time. The wavenumber is the spatial frequency of the wave. The wavenumber is generally used a unit of temporal frequency.

- The full width at half maximum of an atomic absorption line at 589 nm is 100 MHz. A beam of light passes through a gas with an atomic density of 10^17/m3 . Calculate: (1) The peak absorption coefficient due to this absorption line. You can assume that the index of refraction is close to 1 in for this dilute gas. (2) The frequency at which the resonant contribution to the refractive index is at a maximum. (3) The peak value of this resonant contribution to the index of refraction.arrow_forward1a)A sample was excited by the 4358 angstrom line of mercury. Raman line was observed at 4447 angstrom. Calculate raman shift in cm-1. b).

- Infrared Spectroscopy (IR) is very useful for determining the functional groups present in an organic molecule. For each of the spectra below, complete the following: • Build the molecule in Spartan and describe the motion of the molecule at each key absorption frequency • Identify key absorption frequencies in the spectrum and identify the type of stretch/bend/wag/etc. (i.e. O-H) • Match the spectra from the provided structures • Identify the main functional groups in the molecule OH A OH H B E F H N NH2arrow_forwardI want clear handwritten solution only....i will up votearrow_forwardBy what factor will you change the concentration as you monitor the absorbance/transmittance of the solution?arrow_forward
