1: What happens in a molecular level that allows an analyze to absorb light at a certain wavelength. 2: Why are you using a specific wavelength of light to record absorbance measurements for the dye (i.e., why non't every wavelength of light be absorbed by the analyte) I need this answer ASAP please. Thank you

Based on table 1,
why Lmax shifts towards higher wavelengths when you go from
ethylene to b-carotene?
Figure 1. violet blue green yellow orange red purple 500 800 nm The greater the degree of conjugation of chromophores the greater the chance that the absorption of light will occur at higher wavelengths. Table 1 illustrates the effect of conjugation (where max gives the wavelength of maximum absorption): # of conjugated double bonds 175 Table 1.

1. We can observe the wavelengths emitted from Hydrogen. When Hydrogen electrons transition between states, they absorb or emit a particle of light called a photon with energy E=hf. Here f is the frequency of light and h is a constant. a. How much energy does an electron in the n=1 (lowest-energy) state of Hydrogen have? Repeat for n=2 and n=3. b. How much energy is emitted if an electron in the n=3 state transitions to the n=2 state? c....
