David has given you some very large clues though !
Anyway, back to the questions - take a look at this image:
Ask yourself, how would a sensor interpret the greys in the boxes marked A and B ?
We interpret them as A being darker than B, but take the image into photoshop or something and check the RGB values...
It's kind of backwards to the topic at hand, but illuminating nevertheless
