Due tonight.

the distance from one point on a wave to the next similar point is called?

amplitude

frequency

pitch

wavelength

Just look at the words on this list !

-- Amplitude is not a distance.

-- Frequency is not a distance.

-- Pitch is not a distance.

-- Wavelength is a distance !

The distance from one point on a wave to the next similar point is called the wavelength.

tube or goog will be great resources to find the answer to the question that you're asking

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
