Question

assume that you could only see surface A through filter #1. What color would the sample appear to be to your eyes? what about filter #2

Explanation / Answer

if i assume that i could see only surface area A then the sample appear to be to my eyes is mainly yellow having wavelength between 580 nm to 600 nm and reflection ~0.39.

about filter #2:

the wavelength is 940 nm and reflection 0.16 and according to graph this wavelength has not fallen into visible spectrum. it has fallen into infrared spectrum which is not visible in naked eye. thats why no colour will appear to my eyes.
