Calculate the wavelengths, in nanometers,of the eight longest Balmer wavelengths using the following equation: v (frequency) = ((mu*e^4)/(8*h^3*c*epsilon^2))*((1/n22)-(1/n21)) = R((1/n22)-(1/n21)). The R is called the Rydberg constant = 109677.5805 cm^-1 for H. For the Balmer series n2=2 and n1=3,4,5,...
Chemical dyes, which selectively absorb some wavelengths of visible light and appear with characteristic colors, are typically large molecules where the distribution of chemical bonds allows some electrons to travel easily from one end of the molecule to the other. These electrons are effectively confined to a one-dimensional box. The wavelengths of light absorbed by the molecule are then related to its length. If a particular dye has a length of 0.90 nm, determine the three longest wavelengths that the...
Which molecule would absorb the longest wavelength of light? Select one: O a. ob. OC. od
A mercury lamp, which emits several discrete wavelengths of light, finds many uses in spectroscopy. Mercury lines are employed as wavelength standards, as UV sources, and historically as excitation sources for Raman scattering. The 435.83-nm light from a mercury lamp is used to irradiate a pure liquid CCl4 sample, and scattered light is observed at 447.57, 442.19, and 440.05 nm (among others.) What CCl4 vibrational wavenumbers correspond to the scattered light observed here? 447.57nm: _____ cm^-1 44219nm: _____ cm^-1 440.05nm:...
