Living on an island in the tropics has guaranteed each of us experience with the ocean. This is one such experience for me. Though I did know that the ocean was colored in the manner that it is because it reflects the sky previous to Concept Physics, that it had the ability to absorb infrared and low intensity electromagnetic waves I did not know. I did not previously realize this because one usually goes to the beach and in the water to cool off. That the ocean actually absorbs the heat from the energy of electromagnetic waves and still be cooler than the air in the atmosphere is testament to its enormous volume. Yay, ocean!
