======================================== Internal Waves n the Deep Ocean ======================================== The waves we see every day are waves on the surface of the ocean, but did you know that there are waves under the ocean floor? If so, how do we know that at a depth of 1 km of the sea there are waves under the seabed? Nowadays, with modern technology for researching the oceans, this is not impossible, but 1400 years ago, in ancient times, this was not possible at sea depths of several kilometers, because people could not dive beyond 20 to 30 meters without oxygen, they could die without breathing if they stayed longer and dived deeper. But about the waves under the sea, which are several kilometers deep under the sea, where the sun can not reach the depths, the sea is in the dark, people can not reach, but about 1400 years ago, there was a mention of the waves under the sea, which most people do not know. Dr. Durga Rao is a marine scientist and professor at the University of Abdul Aziz in Judea. He was asked about a phrase from the Qur'an that read (meaning in Khmer): "Or (those who do not believe and do evil) like the darkness in a deep sea, with great waves covering it, and a great black cloud overshadowing it. This is the darkness that overshadows the darkness when they take their hands off (in the bottom of the sea) they can hardly see it. O show them, that there is no light for them ”(Chapter 24, Paragraph 40). 40 ُمَلُمَاتٍ فِي بَحْرٍ لُّجِّيٍّ يَغْشَاهُ مَوْجٌ مِّن فَوْقِهِ مَوْجٌ مِّن بٌابٌ ۚ ظُلُمَاتٌ بَعْضُهَا فَوْقَ أَخْرَجَا أَخْرَجَ يَدَهُ لَمْ يَكَدْاهَا ۗ وَمَن لَّمْ يَجْعَلِ اللَّهُ لَهُ نُورًا فَمَا لَهُ نُّورٍ 40 - 40 Dr. Dougarao replied that science now recognizes and confirms the Internal Waves at the depths and depths of the sea, using sophisticated scientific instruments to search for waves under the ocean floor. Darkness in the Deep Sea This layer of darkness is due to two reasons: The sun's rays emit seven colors. This color is caused by the phenomenon that the sun's rays reflect off the surface of the water. At a depth of 10 to 15 meters, the light reflected into the sea is red, at a depth of 30 to 50 meters is already blue, at a depth of 50 to 100 meters is yellow, at a depth of 100 to 200 meters is green and at a depth of 1000 meters and above it will be darker, darker, no light at all. 2. The sun's rays are absorbed by the cloud, causing a dark layer below the cloud's surface. This is the first dark layer. And as the sun continues to touch the surface of the ocean and it bounces off the surface of the water, causing another layer of black opacity, and the sunlight that penetrates into the depths of the ocean and does not reflect, it creates another shadow of darkness, so that the sea has two parts, the bright and warm part and the deep part of the sea is dark. The oceans also have two separate waves, one on the surface of the sea and the other on the depths of the sea covered by different densities (Internal waves at the surface between two layers of water of dfferent denstes).
