Most sunlight consists of what parts of the electromagnetic spectrum?
The visible spectrum (the radiation we can see as light). This is most likely why organisms evolved to be able to see visible light over other types of electromagnetic radiation - the sun emits this more than the other frequencies, so it was easier for life to evolve seeing this spectrum.
What is a lumen?
a measurement of the amount of visible light.AnswerA lumen is the photometric SI unit for luminous flux -i.e. the rate at which an object emits visible light. By 'visible light', we mean electromagnetic energy perceived by the human eye, and the lumen is based on the frequency of green light, to which the human eye is most sensitive.
What is the relationship between visible light spectrum and your sight?
Sight can only be possible in the presence of light. To be able to see an object, we either see the light which it emits, if it is a luminescent object, or the light which reflects off it, if it is a non luminescent surface.
What type of light does photosphere emit?
The photosphere emits the visible light from the sun.
Why aren't black lights black?
Black as a color would absorb all visible frequencies of light. A "black light" is not actually black, but rather emits most of its light in the ultraviolet frequencies. This light is invisible to our eyes except that it interacts with certain materials that fluoresce (glow in the dark) when they absorb UV light. These lights are also used for indoor plants that need UV light to grow.
Are you able to see an object when it emits or reflects one or more visible light frequencies?
Yes.
Why do object appear white?
A white object emits light in all/most of the visible spectrum evenly.Because it reflects all the light back.
If an object emits or reflects light?
It can be seen by the eye.
What is black made out of?
A object appears black when it reflects or emits no visible light. True black is very uncommon because almost no substance can completely absorb light. http://en.wikipedia.org/wiki/Black
Why don't we use visible-wavelength telescopes to locate neutron stars?
A neutron star emits most of its energy at higher frequencies.
do moon reflects light or emits?
it reflects
Is color a property of an object?
Yes. The colour of an object is determined by what frequenc(y/ies) of electromagnetic wave it emits in the visible spectrum. The colour of an object is a physical property of that object.
Why is the statement the color of an object depends on the wavelengths of light it absords inaccurate?
...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
Does color have a suffix?
No, color does not have a suffix. It is a standalone word that refers to the visual appearance resulting from the way an object reflects or emits light.
Is gold non luminous object?
sun (a luminous object) emits its own light and the moon ( a non luminous object ) reflects the light from the sun to earth that's how we can see the moon. The same way gold is a non luminous object.
How do bats know where there pray is?
echo location The bat emits a squeak, which when it reflects (echo) off an object (prey) the bat can hear that and fly to it.
Is Jupiter a luminous or non luminous planet?
Jupiter is not luminous in that it emits light, it reflects the Suns light so that it is visible to us on Earth. See also Albedo.
