Wavelength divided by degree?

  1. Dec 1, 2014 #1

    If c(velocity)/f(frequency) = wavelength
    and 1/f(frequency) * 6 = degrees
    What does Wavelength/degree mean??

    I suspect that "6" is an approximation of 2π.

    I think 6 is the right number to find the degree. It's based on 6 degrees is 1 second.

    You could write the full problem or description rather that expecting people to guess what are you talking about.

    Hi bitencrypt. That's a novel connection indeed! Full marks for originality, at least. Can I guess you are in early high school?

    There are 60 seconds in a minute, and 60 minutes in a degree, these all being angular measures. Not to be confused with time measures co-incidently bearing the same name. .:oldcool:

    360 degrees / 60 = 60 seconds / 60 = 1 second.
    therefore, there are 6 degrees in 1 second (6 * 60 = 360)
    1/f(frequency) = cycle time * 6 = degrees.
    And c(velocity)/f = wavelength

    You may be talking about the motion of a clock's arms. Maybe the second arm. But in this case the wavelength has no connection.
    You should start by describing the system you are talking about before you throw some random formulas. It is really unreasonable to expect people to read your mind.

    Unfortunately, some of your mathematical expressions will mean nothing to anyone here; they are invalid. There is a basic universal restriction to only one equals sign in an algebraic equation. There is no such thing as a progressive equation, or whatever it is you seem to have invented. Please rewrite your expressions so they are valid equations. Observing sound mathematical rigor is a good habit to get into earlier rather than later---I presume you have at least some interest in science, anyway, to have found your way to this forum.

    Also, I suggest using the words "arcseconds" and "arcminutes" when referring to angular measures, so there is no temptation to equate them to measures of time.

    Also, use complete units. The 360 deg / 60 should probably be (360 deg/rev) / (60 sec/rev), for example. Then you won't end up with unitless numbers and unit mismatches.

    I'm also wondering what the OP is talking about.

    Standard angular measurements in degrees:
    360 degrees / 60 = 6 degrees.
    1 degree / 60 = 1 arcminute
    1 arcminute / 60 = 1 arcsecond. (1/3,600th of a degree)

    The fact that a clock's second hand moves 6 degrees per second has no bearing on angular units.
