Yes. Every real thing you see is the result of actual light
that enters your eye and is absorbed by the retina.
The LED itself is visible, the light it emits is not. You can "see" the light by looking at it through a camera, for example the one on your cellphone!
The Earth produces very little visible light itself. However, it is illuminated on one side by the strong light of the Sun.
Visible light does not have watts as a direct measurement, since watts (W) quantify power, not the light itself. However, the power output of a light source can be measured in watts, indicating how much energy it emits as visible light over time. For example, a typical incandescent bulb might produce around 800 lumens of visible light with a power consumption of about 60 watts. The actual amount of visible light (in lumens) produced per watt varies by the type of light source used.
Green is its own color, all by itself.
Thunder itself is not visible. Thunder is the sound produced by the rapid expansion of heated air surrounding a lightning bolt. Lightning, on the other hand, is visible and is the actual electrical discharge that produces the light we see during a storm.
No, heat is not visible to the human eye. We can only see objects that emit or reflect light, but heat itself is a form of energy that is detected by our skin or other instruments.
Many particle physicists, radiation specialists, opticians and ophthalmologists have gotten togetherand named that part of the spectrum the "visible light" band.
Because they Absorb not only the sun light but the energy given off by Saturn itself.
One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.
White light is a combination of all colors in the visible spectrum. When white light passes through a prism, it separates into different colors, creating a rainbow. White light itself does not have a specific color because it contains all colors.
The answer is visible light. Visible light is light that can be seen with a naked eye
No, ultraviolet light is not visible to the human eye. It has a shorter wavelength than visible light, which makes it invisible.
