Question

marine animals most commonly emit light at ______ wavelengths, the wavelengths that travel farthest in clear seawater

Answer 1

Marine animals typically emit light at blue wavelengths, which travel farthest in seawater, and this is related to the phenomenon of bioluminescence.

Step-by-step explanation:

Marine animals most commonly emit light at blue wavelengths, the wavelengths that travel farthest in clear seawater. This is due to the fact that blue light, which has wavelengths around 470 nanometers (nm), is less absorbed by water compared to other colors. The phenomenon of marine organisms emitting light is known as bioluminescence. This adaptation allows these creatures to communicate, attract prey, or deter predators in the deep sea where sunlight does not penetrate.
