An ocean wave has a frequency of 3 waves per second, and the waves are 5 meters apart. What is the speed of the wave?

v = λf = (4 m)(3 Hz) = 12 m/s

Explanation:

so easy. just google the electromagnetic waves and it’ll pop up.

  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.
