El Efecto Doppler, medir si algo se acerca o se aleja en el universo

Sábado 8 de julio 2017. (CienciaES.com).

Christian Doppler(Salzburgo, actual Austria, 1803-Venecia, 1853) Físico austriaco. Estudió en la Politécnica de Viena, y fue director del Instituto de Física y profesor de física experimental en la Universidad de Viena. En su trabajo Sobre la coloración de la luz en las estrellas dobles (1842) ya se incluían los fundamentos teóricos del efecto que lleva su nombre, el efecto Doppler; en él se enuncia que la frecuencia observada de una onda de luz o sonido depende de la velocidad relativa de la fuente respecto al observador. El desplazamiento que se aprecia en el espectro de los cuerpos celestes en función de su velocidad respecto a la Tierra se utiliza para medir su distancia relativa a la misma (BiografíasYVidas.com).

Cuando la fuente de ondas y el observador están en movimiento relativo con respecto al medio material en el cual la onda se propaga, la frecuencia de las ondas observadas es diferente de la frecuencia de las ondas emitidas por la fuente. Este fenómeno recibe el nombre de efecto Doppler en honor a su descubridor.

Huracán (Seudónimo de colaborador de CienciaES.com) nos presenta, a su manera, la idea genial de un científico austríaco de mala salud y malas pulgas con sus alumnos. Su nombre era Christian Doppler (1803-1853), este matemático y físico pensó que las ondas de la luz cambian de frecuencia, o sea de color, si la fuente que las emite se mueve acercándose o alejándose de nosotros. No tuvo suerte con el enunciado de su principio, entre otras cosas porque escogió mal el ejemplo al que supuestamente se aplicaba, pero el tiempo le vino a dar la razón y ahora el efecto Doppler se aplica en muchos campos de la ciencia y la tecnología.

Ésta es la parte “seria” del efecto Doppler, la anédota es la curiosa idea que tuvo el químico y meteorólogo Buys Ballot para demostrarlo. Cuentan las crónicas que Buy-Ballot había sido inicialmente muy crítico con Doppler por su teoría. No obstante, la idea siguió rondándole la cabeza y pensó que, puesto que el sonido también es una onda, si Doppler tenía razón, un sonido emitido por una fuente que se acerca a nosotros debe parecernos más agudo de lo que es en realidad y viceversa, cuando la fuente se aleja de nosotros, debe ser más grave.

Como en aquellos tiempos no había buenos aparatos para medir la frecuencia del sonido, decidió utilizar a expertos en esta materia: los músicos. Reunió a un grupo de músicos conocidos por tener un oído absoluto, es decir, por ser capaces de identificar de oído una nota musical perfectamente afinada, y les pidió que estuvieran en el andén de la estación de Maarssen mientras se acercaba un tren de la línea Amsterdan – Utrech que no paraba en la estación. Debían identificar el tono de una nota musical que estaba tocando un músico montado en el tren, mientras éste se acercaba y cuando se alejaba. Así, “de oído”, comprobó que Doppler tenía razón. Los músicos declararon que la nota subía de tono al acercarse el tren y se hacía más grave al alejarse (lo curioso del caso es que no se le ocurrió utilizar el pitido del tren, como ahora es habitual para explicar el efecto Doppler).

El Huracán ha encontrado otro método, no menos curioso.

    First off I want to say great blog! I had a quick question in which I’d like to ask if you do not mind.
    I was curious to know how you center yourself
    and clear your mind prior to writing. I have had a tough time clearing my thoughts in getting my ideas out.
    I truly do enjoy writing but it just seems like the first 10 to 15 minutes
    are usually lost just trying to figure out how to begin. Any ideas or hints?
    Many thanks! http://nexusfoundation.or.th/?option=com_k2&view=itemlist&task=user&id=91134

  57. An intriguing discussion is worth comment. I believe that
    you need to write more on this issue, it may not be a taboo matter but generally people don’t
    discuss such issues. To the next! Cheers!!

  58. my blog says:

    Hello there! I know this is kinda off topic however I’d figured I’d ask. Would you be interested in trading links or maybe guest authoring a blog post or vice-versa? My blog goes over a lot of the same subjects as yours and I believe we could greatly benefit from each other. If you might be interested feel free to send me an e-mail. I look forward to hearing from you! Awesome blog by the way!

  71. I think that what you posted was very reasonable. However,
    what about this? what if you typed a catchier title?
    I am not saying your content is not solid., but suppose you added something to maybe get folk’s attention? I
    mean El Efecto Doppler, medir si algo se acerca o se aleja
    en el universo – LeoNoticia is kinda boring.

    You ought to peek at Yahoo’s home page and see how they write
    article titles to get viewers to click. You might try adding a video or a picture or two
    to get readers excited about everything’ve written. In my opinion, it would bring
    your blog a little bit more interesting.

  72. Why visitors still use to read news papers when in this technological world the whole thing is available on web?
