Answer the Following What is AC? What is DC? How are they different? What is electromagnetism? When creating an electric motor, what was different between the two “arms” on our wire loops? Why did we do this, and why was it so important?

Light

How do we see light? What is there besides light?

Seeing is believing We do not see everything UV LIGHT =
