Agroup of atoms with aligned magnetic poles are known as which of the following?
a. current
b. poles
c. domains
d. fields

The correct answer is option C. "domains".

Explanation:

The regions within a magnet at which the magnetization is in a uniform direction are known as magnetic domains. These domains are group of atoms with aligned magnetic poles, this means that the magnetic moments of the atoms are aligned and that their point to the same direction. The magnetic domains are the ones that give the magnetic behavior of ferromagnetic materials.

c)as speed changes, wavelength and frequency change.

everything changes!
