THE solar radiation spectrum does not normally extend into the 5-metre wave-length region with sufficient intensity to be detectable on radio receiving equipments in commercial or Service use.

In the study Modelling and analysis of the influence of solar spectrum on the efficiency of photovoltaic modules, published in Energy Reports, the researchers proposed a method to obtain the ...

“The visible part of the solar radiation spectrum hits the pyramidal structure of the concentrators, and, being repeatedly refracted in them, due to internal reflection, concentrates on the ...

But even when solar activity is not visible to the naked eye, the body can still be affected by changes in the electromagnetic radiation spectrum, she said. People with chronic diseases who are ...

Amid a steady stream of galactic cosmic rays and solar energetic particles raining down on planes, the higher altitude and latitude of flights, the higher radiation doses for crew and passengers.
