Main Question or Discussion Point
why is the light from the sun called white light?????????
Yes, and that can mean that (1) the receptors in your eyes respond more intensely to yellow/orange light than to other colours; (2) the Sun indeed emits MORE yellow/orange light than others; (3) or both.but the sun glows on orange colour does not that mean that it is emitting light of orange colour
The sun emits more yellow than any other frequency, and the sun only appears red/orange in the sky because the atmosphere is blocking out the other frequencies more intensly.Yes, and that can mean that (1) the receptors in your eyes respond more intensely to yellow/orange light than to other colours; (2) the Sun indeed emits MORE yellow/orange light than others; (3) or both.
There are many other things to take into account if you want a more thorough understanding of that, as for instance the scattering of higher frequency light (sp. violet and blue) by the N2 and other molecules of the atmosphere (which gives us the blue of the day sky, incidentally), or the combined effect of the three different kinds of photochemical receptors in the retina.
The color that you see when you look at the sun is actually closer to yellow than to orange. That is because the shorter wavelength blue light is scattered by the atmosphere to a much greater degree than the other wavelengths. This is what makes the sky blue. The sun then appears yellow because white - blue = yellow.but the sun glows on orange colour does not that mean that it is emitting light of orange colour
No. The color of light refers to the wavelength of the photons, and there are no "white" photons. When all of the colors in the spectrum are present at equal intensities, then we perceive the result as the color "white". In physics, "white light" is loosely used to mean a few different things, but it typically means light having a broad frequency range covering most or all of the visible spectrum.mmmmmmmmmmmmm this might sound stupid but is the light from the sun litarally white????
Yes, but AFAIK that just a "common" designation for stars in a particular mass/temperature range, and is a reference to the average maximum in the solar http://www.soultek.com/blog/uploaded_images/solar_spectrum_captured_by_new_solar_technology-735670.jpg". The appearance of the sun to the human eye is determined by the integration of the entire visible solar emission spectrum, convoluted with a "detector function", that depends on atmospheric effects, and the wavelength-dependent sensitivity of the human eye (or any other detector). I don't actually know what color the sun would look from space, but from the emission spectrum, I would guess that it looks green or greenish-yellow to the human eye.Just to clear things up a little: The sun is still a "yellow" class star, even before the scattering of its light in the atmosphere makes it appear even yellower than it otherwise would be.
