The minimum frequency of light needed to eject electrons from a metal is called the threshold frequency, ν0. find the minimum energy needed to eject electrons from a metal with a threshold frequency of 5.64 × 1014 s–1.

  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.
