Varying wavelengths, or colours, are absorbed at differing depths; organic matter also adding to this absoption.</p> <p><a href="http://tnl-6.local/node/230" target="_blank">read more</a></p> http://tnl-6.local/node/230#comments English Tentsmuir Water elektromagnetic Waves Sat, 24 Nov 2007 18:06:48 +0000 Lindsay 230 at http://tnl-6.local http://tnl-6.local/node/229 <a href="/node/229"><img src="http://tnl-6.local/files/images/underwater-light.thumbnail.jpg" alt="Sea Pool" title="Sea Pool" class="image image-thumbnail " width="100" height="75" /></a> http://tnl-6.local/node/229#comments Elektromagnetic Tentsmuir Water Waves Sat, 24 Nov 2007 18:04:19 +0000 Lindsay 229 at http://tnl-6.local http://tnl-6.local/node/228 <p>If water absorbs <a href="http://www.thenextlayer.org/node/230">light wavelengths</a> at differing depths, giving the appearance of either a green or blue topography, would a shadow created at the surface still be visible at depth as long as there is light? Is a shadow in effect a Faraday cage for visible light, creating a negative space or an absence, a 'border' through which this type of electromagnetic energy cannot pass?</p> <a href="/node/228"><img src="http://tnl-6.local/files/images/sea-shadow.thumbnail.jpg" alt="Sea Shadow" title="Sea Shadow" class="image image-thumbnail " width="75" height="100" /></a> http://tnl-6.local/node/228#comments Elektromagnetic Tentsmuir Water Waves Sat, 24 Nov 2007 17:11:15 +0000 Lindsay 228 at http://tnl-6.local
