Except that most of what you call real effects is visual; we se something and react to it. The real effects from other (near-visual) parts of the spectrum is quite limited.
I mean; can/does emitted spectrum interact with other parts of our body than just only via eyes? If yes, how this effect can be differnt from effect via eyes?
Can't there be differance in pattern/arrangement of wavelengths in emission spectrum of any molecular structure with same elements in it?
No.
I mean; can there be differance in two emission spectrum's pattern in their chemical formula is same but structure arrangement of their atoms is differant(if it can be possible?). Is it not so that emitted wavelengths travel in line of direction of its emissions?
Does spectrum is in accordance to wavelengths as rainbow, or in accordance to how/in which line wavelenths are emitted?
I don't understand the question.
Does a spectrum is formed in accordance to wavelengths or in accordance to line/direction of emissions of wavelengths?
Don't our body produces energy/ies within it & without exposure to light?
No energies are produced. But our body transfers, converts, and stores energy in a number of ways, mostly chemical.
I mean; do we get outer & internal energies by reflections of colour/wavelength's on their exposure to light? Can we think some light can pass via our skin to internal portion of our body?
Furthur, how can natural sunlight (also of morning/evening), white light emitted by tubes & yellow light emitted by burning oil lamps/candles can be differanciated? Are these as per colour differance--as yellow light from burning oil lamp/candle is just yellow wavelength?
Also; we can get differant colours of any substance on its visual physical look & on burning it? How emission specturm will behave by its exposure to white light & by burning it?
