CHE SIGNIFICA SHADOW BANDS IN INGLESE
Shadow band
Le bande ombreggiate sono sottili linee ondulate di luce alternata e scura che si possono vedere in movimento e ondulare in parallelo su superfici colorate immediatamente prima e dopo un'eclisse totale del sole. Sono causati dalla sottile fessura solare a forma di fessura che illumina l'atmosfera terrestre prima e dopo la totalità dell'eclissi, il loro movimento è causato dai venti atmosferici. Nel 2008, il dottor Stuart Eves ha suggerito che le bande di ombre possono essere causate da infrasuoni, che coinvolgono l'ombra della luna in velocità supersonica, che a sua volta produce un suono a bassa frequenza che gli umani non possono sentire. A causa di questo, ha teorizzato, il movimento della luna crea un'ondata d'urto davanti all'ombra, che provoca fasce d'ombra. Il dottor Eves ha detto: "Se dimostrato, sarebbe una rivelazione che le eclissi sono un sonismo e un fenomeno ottico". Il professor Brian Jones ha dichiarato "La teoria funziona, non c'è bisogno di cercare un'alternativa". Le fasce di ombra sono state osservate in tutta la storia: ▪ Nelle fasce d'ombra del IX secolo, durante una totale eclissi solare, sono descritte per la prima volta - nel Völuspá, parte dell'antica edda poetica islandese.
definizione di shadow bands nel dizionario inglese
La definizione di bande d'ombra nel dizionario è onde lente di luce e buio che si muovono attraverso le superfici di colore chiaro sulla terra appena prima e dopo la totalità in un'eclissi solare. Si pensa che provengano dagli effetti della rifrazione atmosferica irregolare.
