Rayleigh spredning
WebOct 3, 2011 · Rayleigh waves are formed under the conditions where multiple reflections of P and S waves sum up to make a bigger, slower (group velocity) wave which expands cylindrically. Also, Rayleigh waves are "surface waves", which means that they only propagate at and a few hundred km below the surface (they get weaker with depth). May …

WebDe fleste af de spredte lys vil bevare sin oprindelige frekvens - dette er kendt som elastisk spredning, Rayleigh scattering være et eksempel. En lille del af det spredte lys har en frekvens mindre end det indkommende lys og en stadig mindre del vil have en højere frekvens - dette er kendt som uelastisk spredning. WebRayleigh-spredning er betegnelsen for spredningen av blått lys i atmosfæren. Derfor er himmelen blå. Den er oppkalt etter Lord Rayleigh som oppdaget effekten. Fenomenet …

WebFeb 9, 2024 · Spredningen, som favoriserer det blå lys, som har kortere bølgelængde end for eksempel det røde lys, kaldes for Rayleigh-spredning. Det er også årsagen til, at man kan opleve røde solnedgange, da solstrålingens vej gennem atmosfæren dér er så lang, at det kun er den mest standhaftige farve, der er tilbage – nemlig rød.
WebFeb 1, 2009 · Rayleigh-spredning, (efter lord Rayleigh), lysspredning, hvor lyset spredes elastisk, dvs. uden frekvensændring, ved vekselvirkning med partikler, der er små … WebHvis du ber en unge om å tegne sola vil den mest sannsynlig bli farget gult. Men, er sola egentlig gul? Det er nemlig jordas atmosfære som gjør at vi oppfatter sola som gul grunnet en effekt kalt Rayleigh-spredning. I denne episoden skal vi lære mer om hvilken farge sola egentlig har. Kilder: ScienceABC.com, Wikipedia, Store norske leksikon.
