Back

Translucent materials allow some light to pass through but scatter it, while transparent materials allow light to pass through without scattering.

Front

What happens to light when it hits an opaque object?

Back

When light hits an opaque object, it is either absorbed or reflected, but it does not pass through.

Front

What is the role of light in determining whether an object is opaque, translucent, or transparent?

Back

The role of light is crucial; it determines how much light can pass through an object, which defines its classification as opaque, translucent, or transparent.

Front

How can you test if an object is transparent?

Back

You can test if an object is transparent by placing it in front of a light source and checking if you can see through it clearly.
