How is sunlight composed of energy that is visible to humans and energy that is not visible to humans?
Sunlight is composed of a spectrum of electromagnetic radiation, ranging from ultraviolet (not visible) to infrared (not visible) to visible light. The portion of the spectrum that is visible to humans falls within a specific range of wavelengths, which is why we can perceive it as light. Ultraviolet and infrared light have wavelengths outside of the visible range, which is why we cannot see them.
Is the suns energy a form of light energy?
The sun produces electromagnetic energy in many different wavelengths including those within the spectrum visible by humans (i.e. visible light). This energy is the result of an intense nuclear fusion reaction in the sun's core.

What do humans see different wavelengths of as light?
Humans can see different wavelengths of light as different colors. Shorter wavelengths appear as violet and blue, while longer wavelengths appear as red and orange. The entire spectrum of visible light includes colors from red to violet.
Why can humans only see visible light?
Humans can only see visible light because our eyes are equipped with photoreceptor cells that are sensitive to the wavelengths of light within the visible spectrum. Other wavelengths of light, such as ultraviolet and infrared, are not detected by these cells, so we are unable to see them.
What is the only electromagnetic spectrum that humans perceive with their eyes?
The wavelengths which comprise visible light.
What kind of energy enables us to see?
Light, for humans "visible light" which is a form of electromagnetic radiation with a relatively wide range of wavelengths. The absorption or reflection of the various wavelengths of light by objects are what define their color.
Are microwaves visible to humans?
No, microwaves aren't visible to humans. Microwaves are electromagnetic energy, and the only electromagnetic energy humans can see is that of visible light.
What is the human vision wavelengths range?
Human vision is sensitive to wavelengths of light ranging from approximately 400 nanometers (violet) to 700 nanometers (red). This range of visible light is known as the visible spectrum. Beyond these wavelengths, humans cannot perceive light directly.
What types of light humans cant see?
Ultraviolet light and infrared light are two types of light that humans cannot see. Ultraviolet light has shorter wavelengths than visible light, while infrared light has longer wavelengths. Both types of light are beyond the visible spectrum for humans but can be detected with specialized equipment.
Why can wavelengths of light be seen by humans?
Wavelengths of light fall within the visible spectrum, which is the range of electromagnetic radiation that the human eye is able to detect. Photoreceptor cells in the retina convert light energy into electrical impulses that are interpreted by the brain as different colors.
What wavelengths can humans see?
Visible Light is the name of the wavelength range that the human eyes can see. The range is about 400 -700 nanometres (nm) and a colour range of violet through to red. The human eye is not capable of "seeing" radiation with wavelengths outside the Visible Spectrum. However there is some stuff going around that children can see ultraviolet. I don't know if it true, but still.
