Why is the wavelength of 633 nm used to analyze the standard solutions and drink samples? Group of answer choices

The lower the wavelength, the blue solutions will absorb more light.

Corresponding with orange light, is the wavelength that blue solutions absorb the most.

Corresponding with blue light, is the wavelength that blue solutions absorb the most.

The higher the wavelength, the blue solutions will absorb more light.

Corresponding with orange light, is the wavelength that blue solutions absorb the most.

Explanation:

When light is passed through a solution of a particular color, light of other wavelength or color, is absorbed and disappears, whereas the wavelength of light corresponding to the color of that solution is transmitted. The color of light absorbed the most is that which is complementary (opposite it in the color wheel) to the light which is transmitted. In a color wheel, blue is complementary to orange color, red is complementary to green and yellow is complementary to violet.

Therefore, in a blue substance (as in the blue solutions), there would be a strong absorbance of the complementary color of light, orange. Since the wavelength of orange color of light is between 600 - 640 nm, with maximum absorbance of orange light occurring around 633 nm, the wavelength of 633 nm is used to analyze the standard solutions and drink samples.
