Two very large parallel sheets are 5.00 cm apart. Sheet A carries a uniform surface charge density of -8.10 μC/m2 , and sheet B,
which is to the right of A, carries a uniform charge of -13.0 μC/m2 . Assume the sheets are large enough to be treated as infinite.Part AFind the magnitude of the net electric field these sheets produce at a point 4.00 cm to the right of sheet A.Part BFind the direction of the net electric field these sheets produce at a point 4.00 cm to the right of sheet A.Part CFind the magnitude of the net electric field these sheets produce at a point 4.00 cm to the left of sheet A.Part DFind the direction of the net electric field these sheets produce at a point 4.00 cm to the left of sheet A.Part EFind the magnitude of the net electric field these sheets produce at a point 4.00 cm to the right of sheet B.

Answer:
critical angle is the angle of incidence in optically denser medium, for which the angle of reflection in the less denser medium is 90 degree
Explanation:
total internal reflection occurs at one particular angle of incidence where the reflected ray lies on the boundary.
this angle is called the critical angle
