The electric field is strongest where equipotential curves are:.A) closest togetherB) farthest apartC) most nearly straightD) most curvy

A closest

Explanation:

This is because the electric field will be strongest or largestwhen the equipotential curves are closest together

We know that the field is

E= V/d

Where is distance and we see that d being the denominator will only make E bigger if it becomes smaller that is the curves closest

c)as speed changes, wavelength and frequency change.

everything changes!
