Why does water appear cyan?1.Water molecules strongly absorb infrared light, which makes water sppear cyan.2. Water molecules absorb more blue light than any other light.3. At normal temperature water gives out more blue light than any other light.4. blue light from the sky is reflected by the surfave of water.5. Water molecules resonate somewhat in the visible red, causing red light to be absorbed easieer than blue light in water.
Number 5 is the only correct answer. 1 is incorrect because absorbing infrared light would make no difference because infrared is invisible. 2 is incorrect because if water absorbed blue light it wouldn't reflect it and it would be red. 3 is incorrect because water doesn't give out light it only reflects light 4 is incorrect because water is always blue (the sky is blue due to light scattering by the way) 5 is correct follow the source.
