Fill in the following blanks.
As the dye concentration increases, the absorbance of the light [linearly increases, linearly decreases, exponentially increases or exponentially decreases].
The dye concentration units are [molar (M), millimolar (mM) or grams per liter (g/L)] .
Although most people wrongly conclude that absorbance has units nm, in fact, absorbance is unitless. This is because it results from a ratio of light through a colored sample relative to light intensity through a clear (blank) sample.
The units for the slope of the graph would be [mM, 1/mM or nm] . Hint: the slope is the change in y values divided by the change in x values.
The units for the y-intercept of the graph would be [nm, nM or unitless] .
The value for the slope of the line that describes the absorbance data is [6.4597 or 0.0008]
The value for the y-intercept of the line that describes the absorbance data is [6.4597 or 0.0008] .
3. A prism is anle to differentiate the colors of the rainbow via refraction. The spectrometer uses a surface called a diffraction grating, which reflects light of various wavelengths at different angles. Give a real life example of an object or substance which acts as a diffracting grading, explain your reasoning.
