Sunset in the Tyrrhenian Sea (1 SBD quiz inside)
This magic moment
Earth rotation gently carrying us
into the twilight zone.
Assiduous molecules
and airborne dust,
eagerly scattering away
the green and the blue,
photon by photon.
Red alone
and it's long-waved companions
they are allowed to pass,
largely unhindered,
to the joy of our eyes.
;)
After which Nobel Laureate was the scientific phenomenon named, which I elaborated in this (attempt of a) poem? 1 SBD for the Steemian who provides the correct answer first.
Thanks for watching and 'til next time!

Rayleigh. If I'm right, kindly send the 1SBD to @church-of-piglet.
Good shots, more difficult than it looks at first glance 8-).
Lord Rayleigh, indeed!
A messenger is on his way to the @church-of-piglet , with a full SBD in his saddlebag :)
Blessings be upon you! If only every Steemian would do this, we could finally fix the Learjet.
Venkata Raman. https://en.wikipedia.org/wiki/Raman_scattering
Thank you for participating in this little quiz!
The light scattering that was named after Sir Venkata Raman does occur in the atmosphere, too. However, it's contribution to the red-shift of light observed during sunset (and sunrise) is hardly appreciable (by eye). This effect is mainly caused by the light scattering named after John William Strutt, 3. Baron Rayleigh (<- correct answer).
Both types of scattering are related yet differ in a key aspect. Raman scattering is associated with energy transfer between the photon and the scattering molecule resulting in a shift of the photon's wavelength (or color so to say), whereas Rayleigh scattering only changes the direction of the incoming photon without changing it's energetic state (i.e. color). Light with short wavelengths (perceived as green and blue shades) are scattered more strongly and thus are removed from the incoming sunlight.
I thought you made a typo because that name is so long, but no his name is actually "John William Strutt, 3rd Baron Rayleigh"!
Thanks for the physics insights!
Raman scattering
Raman scattering or the Raman effect is the inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels.
It was discovered by C. V. Raman and his student K. S. Krishnan in liquids,
and independently by Grigory Landsberg and Leonid Mandelstam in crystals.
The effect had been predicted theoretically by Adolf Smekal in 1923.When photons are scattered from an atom or molecule, most of them are elastically scattered (Rayleigh scattering), such that the scattered photons have the same energy (frequency and wavelength) as the incident photons. A small fraction of the scattered photons (approximately 1 in 10 million) are scattered inelastically by an excitation, with the scattered photons having a frequency and energy different from, and usually lower than, those of the incident photons.
i like ramen. mmm.... ramen... oh... wrong person XD
Greetings @shaka,
Lovely photographs......just splendid.
The poem is well done, thoughtful and serene.
All the best to you from bleujay/bentleycapital
Cheers!
Perhaps @ocrdu has the answer......really do not know.
Thank you @bleujay! As you rightly assume, @ocrdu got it right.
Wilhelm Conrad Röntgen
Thank you for participating in this Quiz!
Hardly anything has advanced modern medicine more than the discovery of X-rays by Röntgen. It has no impact on the beauty of sunsets though :)
Das nenne ich einen "Sunset Deluxe"! ;-)
Danke, das ist tatsächlich einer der Besten, den ich einfangen konnte :)
Coming too late to compete in the quiz again (damn! :D) but those sunsets shots are incredible @shaka. I never capture the sun that big in my photos...
Btw, you have some decent poetry skills too! :D
Thank you!
Key for those sunset shots is to strongly underexpose so that the sun still has some color and retains it's contours. Everything else then is pitch black and needs to be exposed in post-editing. If you look closely you can see that the dark parts in my shots already become somewhat noisy, so there is obviously a limitation to it (with standard equipment like I'm using).
Sounds good, thank you - will try next time :) So far, I have mostly ended up with something like this:
It does not look too bad I think but the size and sharpness of the sun is a far cry from yours...
Beautiful!
Sir Isaac Newton? :) Wohl eher nicht, den Nobelpreis gabs ja damals noch nicht.
Ich mag Rätsel. Als Kinder haben wir uns oft diese Geschichten gemerkt, die ungefähr so gingen:
Drei Männer liegen tot auf Erde. Einer von ihnen hat ein Stück Streichholz in der Hand. Wieso?
Deine Ode an das Farbenspiel erinnert mich an die Mondfinsternis, die in ebensolchen Farben zu sehen war und mich ehrfürchtig machte.
Der gute Newton ist ja kaum genug zu würdigen aber im Bereich der Lichtstreuung hat er sich meines Wissens nach nicht hervorgetan. Sicher beobachtend aber zur Beschreibung dürfte das Wissen um die Quanten gefehlt haben.
Keine Ahnung :D. Ein Stück Streichholz klingt danach, dass jemand den Kürzeren gezogen hat. Aber warum hat es dann alle drei erwischt?
:-))))))) ganz Recht. Es dürfte nur ein Toter auf der Erde liegen. Ich habe im Geist die Geschichte gemixt und das Ende dann falsch erzählt. Meine Erinnerung war nicht zum Besten.
fantastic shots shaka..
I love sunset photographies..
here is mine
:D
Such a great contest
Thats are my photography
Hello Shaka! beautiful pictures, no idea of the correct answer, but grateful for motivating the community.
