1) a sound wave with a frequency of 300 hertz is traveling through a medium at a speed of 320 meters/second. what is its wavelength?

2) a sound wave has a wavelength of 0.450 meters. if its speed in cold air is 330 meters/second, what is the wave's frequency?
a.0.890hertz
b.100hertz
c.230hertz
d.733

1. The wavelength is the ratio of the wave's speed to its frequency in hertz or 1/s. This is shown below,

                          λ = s / f = (320 m/s)  / (300 1/s) = 1.07 m

The wavelength is approximately 1.07 m.

2. The frequency is the ratio between speed and the wavelength,

                       f = (330 m/s) / 0.45 m = 733.33 hertz

a.) is the correct answer.

explanation:

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
