Answer:
values the transmittance or absorbance is plotted on the y axis, dependent variable and the wavelength on the x axis, independent variable.
Step-by-step explanation:
The absorbance or transmittance measurements (T) determine the amount of light that passes through a material (I) and divide it by the amount of light that passes without the material (Io), to see the values the transmittance or absorbance is plotted on the y axis, dependent variable and the wavelength on the x axis, independent variable.
