Relative Posted April 6, 2014 Author Posted April 6, 2014 Good instinct. It's one you should lead with. There are a lot of physics books out there where you can gain understanding. I don't know what you mean by layered, seeing as you've not brought this up before. On explaining else where, they explained that all the spectrum from the Sun , the different waves were layered like a laser works. Where as I think sort of interwoven, and a ''constant oscillation'',my definitions>, My evidence is when we oscillate the spectrum colours we see white, If we could add higher energy we would get a much higher contrast. Shown in my youtube vids. I think the transparency is because our eyes adjusted to the flicker as such, the constant oscillation. And when we see effect of a prism , we are making a set modulation. By angle , angle defining the length. Similar with rainbows and diffraction etc.

No, light from the sun is not a whole lot like a laser. Lasers are a special case where the light is coherent and fairly monochromatic. Sunlight is neither.

Sunlight is neither. Thank you I did not think it was like a laser, did not make sense. So what do the waves look like been emitted from the Sun, if we could see the waves and they were not transparent to our sight? What sort of formation would it have? or grouping?
Sensei Posted April 6, 2014 Posted April 6, 2014 The first of all Sun is emitting photons in the all directions uniformly. It's called isotropic emission: http://en.wikipedia.org/wiki/Isotropy Equally in the all directions. Similar is working f.e. light bulb. Read about inverse-square law, if you have not already http://en.wikipedia.org/wiki/Inverse-square_law Sun is emitting photons with whole range of frequencies/wavelengths/energies (what you prefer), except few missing (spectral lines of various atoms). http://en.wikipedia.org/wiki/Spectral_line Which allows us to tell what atoms are in given star and in what concentration. You can see Sun spectrum in this article http://en.wikipedia.org/wiki/Sunlight This is also useful in modern chemistry to tell components of substance: http://en.wikipedia.org/wiki/Spectroscopy Laser is pretty much directional source of photons. With very short frequency/wavelength range. f.e. mine green laser 100 mW with 532 nm has tolerance +-10 nm (so it should emit photons between 522 nm to 542 nm).

The frequencies would be pretty close to a blackbody spectrum. It would not be coherent.
Relative Posted April 6, 2014 Author Posted April 6, 2014 Brilliant links etc, thanks a lot, And I think after two years finally an answer I understand. ''The frequencies would be pretty close to a blackbody spectrum. It would not be coherent. '' does that mean it would be all mixed up , if so then yes that sounds correct.
