    The physics of wave properties on a string

    To get the answer to question e do I divide 125000 / 0.0004 to get the time required for a particle on a string to move through a total distance of 1.0 km which would equal 312500000? If this is right then ignore this question about where does the amplitude fit in?

    The physics of wave properties on a string

    The period is the time to complete 125000 cycles? The period being 4x10^-4s is the answer to question e?

    The physics of wave properties on a string

    I finished (d) by 1000000 mm / 8 mm = 125000 mm For (e) would the answer be 125000 mm = 125 m therefore 125 m / 450 m.s = 0.27 s because the number of cycles is 125000 mm or 125 m and the time for one cycle is 450 m.s? Please correct me if I'm wrong.

    The physics of wave properties on a string

    Dividing by 8 with what? I'm lost. Could you make up an example of the question d and e? I don't understand the questions...

    The physics of wave properties on a string

    Oh, so is this the answer or is there more?

    The physics of wave properties on a string

    62500 cycles because 1 km = 1000000 mm and 1000000 mm / 16 mm = 62500.

    The physics of wave properties on a string

    How did you know to add 4? Or that it was 16 mm per cycle?

    The physics of wave properties on a string

    I'm just guessing but 1000000 because 1 km is 1000000 mm. For starters, the question doesn't make sense to me.

    The physics of wave properties on a string

    The 8 mm must be in m if I'm doing this: 0.18/8 or 0.008 = 0.0225 or 22.5

    The physics of wave properties on a string

    Homework Statement The speed of a transverse wave on a string is 450 m/s, while the wavelength is 0.18 m. The amplitude of the wave is 2.0 mm. a. What is the total up and down distance moved by the wave particle for each cycle of the wave? b. What is the frequency of the wave? c. What is...
