Adaptive Radiation
The crust is typically thicker under the continental shelf compared to under the oceans. This is because the continental crust is made of lighter granite rocks which are less dense than the basaltic rocks of the oceanic crust, resulting in thicker continental crust.
Light doesn't have to be invented. Emitting radiation in the form of light is a naturally occurring phenomena under some conditions.
The radiation in smoke detectors, usually in the form of ionizing radiation from americium-241, is very low and not harmful to humans under normal conditions. The radiation level from smoke detectors is well within safety limits set by regulatory agencies.
The Earth's crust is thinnest under the oceans and thickest in the mountains.

To what, under which conditions?
its under the oceans
sodium is found in salt deposits found under oceans or where oceans once where.
Approximately 400 to 700 nm. The exact range varies, depending on the sources... and indeed, depending on the exact conditions under which the experiment is done.
The layer that is thinnest under the oceans is the crust. While it is thinnest in those underwater regions, it is the thickest in the regions where mountains are.
