What is the critical angle of a diamond having a refractive index of 2.42? use air as the second medium. air has the refractive index 1.00.

a. 14.9°
b.24.4°
c.36.6°
d.40.9°

if they have a finite resultant

  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.
