Which statement describes how rays behave when they travel through media during reflection and refraction

The correct answer  for above statement is:

Reflection is the difference in the path of a wave front at an interface among two distinct mechanisms so that the wave front turns into the medium from which it began. refraction is the variation in the area of a wave crossing from one medium to different or from a continuous variation in the mechanism.

  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.
