WILL MARK Which statement is true for light passing into a medium that is less optically dense than the first medium through which it passed? The index of refraction of the second medium is higher.

The index of reflection of the second medium is lower.

The index of refraction of the second medium is lower.

The index of reflection of the second medium is higher.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
