What is one way that alternating current is more useful than direct current-

It can easily be transformed up to a high voltage for power transmission, and back down for home supplies at 120/240 volts.

What causes refraction-

Refraction is caused by light crossing from one medium to another.

What occurs when two or more waves occupy the same space at the same time-

When two or more waves occupy the same space at the same time, an interference pattern is created.

What produces standing waves-
