If you have red solution, at what wavelengths should it absorb light, at what wavelengths should it NOT absorb light?
A red colored solution transmits red. It absorbs the complement of red. Draw the color wheel and check the color exactly opposite to red.

Ah, the red solution! Well, red is quite the stylish color, isn't it? Now, when it comes to absorption, my dear friend, red solutions generally absorb wavelengths that are complementary to their color. So, a red solution would typically absorb longer wavelengths in the green and blue regions of the spectrum.
As for wavelengths it should not absorb, well, red solutions tend to be picky eaters and usually avoid feasting on wavelengths that match their own shade. So, wavelengths in the red region of the spectrum are the ones that red solutions would most likely not absorb.
But hey, don't take my word for it! Experiment and check it out for yourself. Just remember, even molecules need a little humor in their lives, so keep that laughter flowing in the lab!
The specific wavelengths at which a red solution absorbs or does not absorb light depend on the particular chemical composition of the solution. In general, red solutions absorb light in the blue or green regions of the visible spectrum and do not absorb light in the red region. However, it is important to note that this is a generalization and may not hold true for all red solutions. To determine the exact absorption spectrum of a specific red solution, a spectroscopic analysis such as UV-Vis spectroscopy would need to be performed. This technique measures the absorbance of light at different wavelengths and provides detailed information about the absorption characteristics of the solution.
To determine the absorption properties of a red solution and the wavelengths at which it absorbs or does not absorb light, you can use a spectrophotometer or refer to the known absorption spectra of the specific red solution.
Here's how you can go about it:
1. Obtain a spectrophotometer: A spectrophotometer is a scientific instrument used to measure the absorbance or transmission of light through a substance. It can help determine the wavelengths at which a solution absorbs light.
2. Prepare a red solution: Create a solution using the red substance for which you want to determine the absorption properties. Ensure the solution is properly prepared, dissolved, and free of any impurities that could interfere with the analysis.
3. Set up the spectrophotometer: Follow the manufacturer's instructions to calibrate the spectrophotometer and set it up for analysis. This typically involves adjusting the wavelength range and any necessary baseline corrections.
4. Measure the absorbance spectrum: Take a series of absorbance measurements at different wavelengths across the desired range, typically starting from the UV range and going into the visible or near-infrared range. Record the absorbance values at each wavelength.
5. Analyze the data: Plot the absorbance values against the corresponding wavelengths to generate an absorbance spectrum. The spectrum will show the wavelengths at which the red solution absorbs light and the intensity of absorption.
6. Interpret the results: Look for peaks or regions of high absorbance in the spectrum. These indicate the wavelengths at which the red solution absorbs light. If there are no peaks or very low absorbance, that suggests the red solution does not strongly absorb light at those specific wavelengths.
Alternatively, if the specific red solution you are referring to is a well-known substance with documented absorption properties, you can consult scientific literature or databases for its absorption spectrum. These references provide detailed information on the wavelengths at which the solution absorbs or does not absorb light.
Remember, the exact absorption properties of different red solutions can vary, so it is important to analyze each specific case individually using experimental methods or available reference data.
