The evidence
1 source verse, an interactive observation, and three deliberately separated readings.
The boundary
A resonance is not a scientific prediction. These studies invite reflection; they do not turn scripture into a laboratory manual.

The verses
An-Noor 24:40✦ exploreread أَوْ كَظُلُمَٰتٍ فِى بَحْرٍ لُّجِّىٍّ يَغْشَىٰهُ مَوْجٌ مِّن فَوْقِهِۦ مَوْجٌ مِّن فَوْقِهِۦ سَحَابٌ ظُلُمَٰتٌۢ بَعْضُهَا فَوْقَ بَعْضٍ إِذَآ أَخْرَجَ يَدَهُۥ لَمْ يَكَدْ يَرَىٰهَا وَمَن لَّمْ يَجْعَلِ ٱللَّهُ لَهُۥ نُورًا فَمَا لَهُۥ مِن نُّورٍ
Or [they are] like darknesses within an unfathomable sea which is covered by waves, upon which are waves, over which are clouds - darknesses, some of them upon others. When one puts out his hand [therein], he can hardly see it. And he to whom Allah has not granted light - for him there is no light.
What the text says
The text pictures deeds of the faithless as darknesses in a deep sea: covered by waves, above which are waves, above which are clouds: darknesses one above another; if one puts out a hand, one can hardly see it.
What classical readers understood
Classical readers took the layered image as a parable of compounded misguidance: darkness of the deep, of the waves, and of the clouds stacked one upon another.
What science sees
Seawater absorbs light by color: red is gone within roughly 15 meters, orange by ~30, yellow by ~100, green by ~200; only blue reaches further before fading near ~1000 meters into the aphotic zone, where sunlight never arrives. Internal waves also run beneath the surface waves, a literal wave below a wave.
