Homework Help: Frequency of a Spark Timer, 0.10s

  1. Oct 3, 2004 #1
    Hey, I just signed up and I've already got a question. =)
    The answer was in the book but I don't get the answer.

    Determie the frequency of a spark timer set at a period of 0.10s.
    Ans: 1.0 x 10¹ Hz.

    The book only says;
    The answer is literally staring me right in the face and the explanation might be really easy but for it's just not making sense to me. Can anyone help? Thanks a lot!

    Frequency(in hertz) = 1 / period (in seconds). I can't really explain it any other way without writing several paragraphs but that's mostly to my rambling nature. 1 Hertz = s^(-1) or (cycles/second) depending on how you look at it.

    Since there are 6 sparks in 60 seconds, there is is one spark every 10 seconds. How many sparks per second? Or, even easier, how many sparks per minute?

    Now what does "frequency" MEAN??

    Ah. I think I get it now. Thanks a lot!
