The standard wave format for any wave is
a a transverse
b a longitudinal
c an electromagnetic
wave. When depicting
a a transverse
b a longitudinal
c an electromagnetic
wave in standard wave
format, the direction of motion must be rotated by 90 degrees. Only one of two waves is shown at a time when placing
a a transverse
b a longitudinal
c an electromagnetic
wave in standard wave format

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.
