Below is an absorbance spectrum for a violet/purple the color scale you drew in Question 1, wn dye? Which color(s) is/are most transmitted? olet/purple dye called crystal violet. According to Ich color(s) is/are most absorbed by the violet Absorbance 600 300 400 500 Wavelength, nm 3. Examine the following absorbance spectra. Each line corresponds to the same crystal violet dve measured at different solution concentrations. At approximately which wavelength chould nu measure the absorbance to differentiate between the concentrations of the various dyes? Alysorbance(a.u.) 700 500 600 Wavelength (nm) 400 (OVER)

Answer 1

Ans 1 :

The visible color ranges from 400 nm to 750 nm of wavelength.

It starts violet color at 400 nm and ends at red color at 750 nm.

The boundaries of various ranges of color on wavelength scale is shown below ...
