yes some light rays do reflect from human skin but they are so less that they are almost ignorable. human skin's got pores and so majority of the light rays enter through them. hence human skin does not reflect back light as shiny sufaces like mirror etc. do
(That is the reason why other people are almost invisible to you.)
No, human body doesn't float on helium as it is light.
If an object reflects the entire spectrum of light, it appears white to the human eye. This is because white light contains all the visible colors of the spectrum, and when an object reflects all these colors, it appears white.
No, the human body is not transparent to the visible spectrum of light. Skin, muscles, and other tissues in the body absorb and scatter visible light, which is why we cannot see through the human body like we can with glass.
Yes, the human body does produce light, although it is extremely faint and not visible to the human eye. This light is known as biophotons and is generated as a byproduct of biochemical reactions that occur within the cells of our bodies.
" albedo "
The moon is not shining body because it does not release light of its own. In our solar system, only the Sun is a "shining body." The Moon shines by the reflected light of the Sun.
Human skin produces Vitamin D in presence of sun light but not the other parts of body.
White reflects all colors because it contains all wavelengths of visible light. When white light strikes an object, it reflects back all colors equally, making it appear white to the human eye.
White reflects all colors of light equally, which is why it appears white to the human eye. When white light hits an object, the object absorbs some colors and reflects others, with white reflecting them all.
LED Light is Toxic to the eyes
Yes, I think so. It doesn't let light through, so it's opaque....
ANSWER: It reflects light. The sun is the only body in the solar system to emit light.
