What is the direct cause of green and blue light being visible at greater ocean depths compared to other colors?

Water reflects other colors at the surface.

Water transmits these short wavelengths effectively.

These wavelengths are amplified by salt in the water.

Marine plants produce light in these colors.

A scuba diver brings a bright red object down to a depth of 100 meters, where little sunlight penetrates. Without using an artificial light, how will the object most likely appear?

Bright red, as its natural color is permanent.

A faint blue, as it can only reflect the available ambient light.

Dark grey or black, because the red wavelengths needed to see its color were absorbed by the water far above.

Vibrant green, due to a chemical reaction with saltwater at pressure.

absorb blue light most strongly.

scatter blue light more than they absorb it, allowing it to travel deeper and reflect back.

convert red and green light into blue light through a process called fluorescence.

Red, because it contrasts most with the dark water.

White, because it contains all the colors of the spectrum.

Blue, because its short wavelength penetrates furthest through water.

Yellow, because it is the brightest color to the human eye.
