If light of all visible wavelengths is combined the results appear to be what color?
If the lights from all visible wavelengths are combined, they appear to be a white color.
Why does not white light when falls on objects makes them appear as black or white?
Many objects do appear black or white when light falls on them. If they are black, it means that the object is absorbing all wavelengths of visible light and not reflecting any. If they are white, it means that they are reflecting all wavelengths of visible light and not absorbing any. The color of an object is due to the wavelengths of light that it reflects.
Why black body absorbs heat?
Objects appear white when they reflect all wavelengths of visible light. Reflection of various wavelengths of light means that they are scattering the light back into the space surrounding the object, rather than absorbing that energy.Objects appear black when they absorb all wavelengths of visible light, thus absorbing that energy (some of which is converted to heat).
Why does the color red appear red?
Most of the longest wavelengths (reds) of visible light are being reflected, compared to the other colors. The shorter wavelengths are mostly being absorbed.
Do blue visible light and red visible light have the same wavelength?
No, blue and red visible light have different wavelengths. if you see the rainbow, blue and red can been seen on separate stripes which means they have different wavelengths.
For a substance to appear black and what must happen to all wavelengths of light?
A substance that appears black (in a lighted room) is absorbing all of the visible light that hits it, leaving no visible light to reflect off of it to your eye. So it's absorbing visible light of all wavelengths. (You still don't know what's happening to the infra-red or ultraviolet hitting it. For that, you need to use different detectors.)
What colour does red writing appear in green light?
Things appear red because they absorb all wavelengths of visible light apart from red this will be reflected. If you only shine green light on the object it will all be absorbed and no light will be reflected so it will appear black.
What must happen a substance to appear black what must happen to all wavelengths of light?
A substance that appears black (in a lighted room) is absorbing all of the visible light that hits it, leaving no visible light to reflect off of it to your eye. So it's absorbing visible light of all wavelengths. (You still don't know what's happening to the infra-red or ultraviolet hitting it. For that, you need to use different detectors.)
Whats the difference between homogenous mixture and heterogeneous mixture?
In a homogenous mixture the substance are so evenly distributed that it is difficult to distinguish one substance in the mixture from another but it only contains only one substance and it will appear the same. In a heterogenous mixture the parts of the mixture are noticeably different from one another and the mixture is different and kind.
The color of light is determined by of the light waves.?
The cones in the retina of our eyes are sensitive to certain frequencies of light within the visible light spectrum (ROYGBIV). Light waves with longer wavelengths (within the visible range of frequencies) are perceived to be on the red, orange, yellow side of the spectrum, while higher frequencies/shorter wavelengths of light appear blue or violet.
The leaves of this plant appear to be reddish yellow What wavelengths of visible light are being absorbed by this pigment?
Red and yellow, of course. The light you see is being transmitted and not absorbed.
The energy of wavelengths that appear is least useful to photosynthesis?
green
