Final answer:
Typically, a red light is activated on the aircraft's cabin indication system when the flight deck crew makes an emergency call to the flight attendant. The given options about light and color are educational but unrelated to the emergency signaling protocol used in aircraft.
Step-by-step explanation:
When the flight deck crew makes an emergency call to the flight attendant, a specified light in the aircraft cabin indication system is activated to alert the attendant. Among the options provided, typically a red light is used to signal an emergency or to capture the flight attendant's attention immediately for prompt action. This is a safety protocol observed in the operations of commercial airlines.
This scenario doesn't directly involve the physical properties of light such as wavelengths and frequencies, or the effects of different lights on colored paper. However, it is important to note that in the context of physical phenomena and the study of light, when white light shines on yellow paper, the paper will appear yellow because the paper reflects yellow wavelengths. When yellow light shines on white paper, the paper similarly appears yellow. Finally, when red and green lights shine on a white paper, the paper could appear to be a shade of yellow or white, since red and green lights can combine to form yellow light in the RGB color model used in lighting.
