Question

a technical diver takes a dive to 55 meters deep where they encounter a yellow fish. what color will the fish appear to be to the diver? select choice select choice blue red yellow

Explanation:

When light travels through water, different wavelengths (colors) are absorbed at different rates. Red light has a longer wavelength and is absorbed first as depth increases. Yellow light is a combination of red and green light. At 55 meters, the red component of the yellow light would be significantly absorbed. Green light has a shorter wavelength than red. When the red part is removed from yellow (which is red + green), the remaining dominant color that the diver would perceive is blue (since green light can combine with other remaining light - like the blue - ish tint from water's absorption characteristics in a way that the overall appearance shifts towards blue).

Answer:

blue
