Transparent

Example:

Imagine trying to listen to a friend at a busy café, where the background noise makes it hard to hear them clearly. This is similar to how light interacts with different materials; just as your friend's voice needs a clear path to reach your ears, light needs a clear medium to pass through for us to see objects on the other side. In this analogy, a transparent material, like glass, acts like a quiet room that allows sound (or light) to travel through without interference, making it easy to perceive what's beyond.
