About 47% of the sunlight that reaches the Earth's atmosphere is visible light. Of this, approximately 30% is reflected back into space by clouds, atmospheric particles, and the Earth's surface, while the remaining 70% is absorbed or scattered in the atmosphere. This absorbed light is essential for photosynthesis and drives various climate and weather processes on Earth. Overall, only a fraction of the total solar energy is converted into visible light that can support life.
What else can I help you with?
What wavelengths can astronomers detect from earth?
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
How does the wavelength of gamma rays compare to the wavelength of visible light?
It is electromagnetic radiation, which is the same in composition as visible light but has a much higher frequency/shorter wavelength, and will do damage to any biological material it passes through. Both travel at the same speed ('velocity of light') but gamma radiation can penetrate material opaque to visible light.
What is longer human skin cell or the wavelength of visible light?
The wavelength of visible light is longer than a human skin cell. Visible light has wavelengths ranging from about 400 to 700 nanometers, while a human skin cell is typically around 30 micrometers in size.
How much of the radiation from visible light waves is absorbed as the radiation passes through the atmosphere?
Roughly 20% of visible light radiation is absorbed as it passes through the Earth's atmosphere. The remaining percentage is either reflected back into space or reaches the Earth's surface. This absorption is influenced by factors such as cloud cover, aerosols, and gases in the atmosphere.
Dangers of visible light?
Exposure to high-intensity visible light, such as from the sun or artificial sources, can potentially cause damage to the eyes, leading to conditions like photokeratitis or photoconjunctivitis. Prolonged exposure to blue light, a component of visible light, especially from screens, may also disrupt sleep patterns and cause digital eye strain. Additionally, visible light can contribute to skin aging and pigmentation.
How much of the visible spectrum is contained in white light?
All of it. White light is the blend of all visible colors.
What is the difference between visible light and gamma waves?
Gamma rays are of higher energy and much much shorter wavelength than visible light.

What part of the solar energy reaching the earth is absorbrd by plants and trapped by chlorophyll?
They are the blue and red frequencies of visible light. Green is not absorbed much
How much of the electromagnect spectrum is visible light?
its hey
How much light can the color white absorb?
White does not absorb light - it reflects all visible light waves, while black absorbs all visible light and reflects nothing.
Why can't you use visible light to see molecules?
Visible light cannot be used to see molecules because the wavelength of visible light is much larger than the size of molecules. This means that visible light cannot resolve the small details of molecules, making them invisible to the human eye.
Why is it difficult to see the Sun's corona from Earth?
Because the Sun's photosphere is so much brighter in visible light (most of the light the Sun's corona emits is ultraviolet). It is necessary to block the light from the Sun's photosphere to see the Sun's corona.
