In this International Year of Light, it is particularly appropriate to review the historical concept of what is light and the controversies surrounding the extent of the visible spectrum. Today we recognize that light possesses both a wave and particle n
What is light pollution? What is tangential lighting? What are the types of reflection of light? What are illuminated objects? What is the dual nature of light? What are fluorescent lights made of? What does luminescent mean? What is radiant energy?
How does light interact with matter? What the speed of the dark? How can gravity affect light? In what form does the radiant energy travels? What is a pressure wave? Which is faster, light or electricity? To say that light is quantized means that light is made up of what?
What is solar energy? Simply put, solar energy is the light produced by the sun. The Source of Solar Energy To get technical,solar energy is the radiant energy that the sun produces. This is the result of a process callednuclear fusion- the joining of smaller atoms to form a larger atom...
High Energy Visible Light (HEVIS Light) is all around us. It’spart of the light we can see.It’s been around for as long as UV rays, but while much has been written about their effect on skin, the molecular and visible effect of HEV Light on skin is a more recent discovery. Resea...
iSolar Lighting is a Company Focus on Manufacturing Outdoor LED Solar Lights, Such as Solar Flood Lights, Solar Street Lights. Solar energy is an alternative energy source that involves harnessing the radiant light energy emitted by the sun and converting it into electrical current. Since the midd...
Some German physicists theorized that a single photon (particle of light) has a quantum energy Qν that is directly proportional to the frequency f (sometimes symbolized by the Greek letter, ν) of the wave: Qν = h × f, where h is known as 'Planck's Constant.' This led to the ...

However, most of the solar energy is absorbed or reflected back to the atmosphere and becomes heat. The following summary of the fate of solar energy by Mader (1990) further provides more elaboration on what is light: (1)Only 42% reaches the surface of the earth; ...
Step-by-Step Solution:1. Definition of Solar Energy: - Solar energy is defined as the radiant light and heat that is emitted from the Sun. It is a renewable source of energy that can be harnessed for various
