check What wavelengths of light are being absorbed in Self Check Image 1? What colors of light are being transmitted? Answer

Since the solution appears purple, it is probably absorbing yellow light. Yellow light is in the range 560 nm - 590 nm. The solution is probably transmitting red, orange, green, blue, and violet light (all colors except yellow).

check What wavelengths of light are being absorbed in Self Check Image 2? What colors of light are being transmitted? Answer

Since the solution appears orange, it is transmitting orange light and absorbing blue light (the color opposite orange on the color wheel). However, the orange solution is not transmitting only orange light; it transmits all wavelengths of light which are not absorbed.
