Answer 1

Answer:

When light encounters transparent materials, almost all of it passes directly through them. Glass, for example, is transparent to all visible light.

Opaque objects block light from traveling through them.

Explanation:

An electric circuit is a closed loop through which electric current can flow. A circuit must include a source of voltage and conductors such as wires to carry the current from the source of voltage and back again. Types of circuits are series and parallel circuits
