Compton observed an increase in wavelength with scattered X rays, which meant that the X-ray photons had a. lost momentum only.
b. lost both energy and momentum.
c. gained energy only.
d. gained both energy and momentum.

true is the correct answer

  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.
