Light: Refraction, Reflection, and Absorption

Front

What is the definition of transparent?

Back

Transparent materials allow light to pass through them without scattering, making objects behind them clearly visible.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

Front

What are materials that let some light pass through but not all?

Back

Translucent materials allow some light to pass through, but they scatter it, making objects behind them appear blurry.

Front

What does opaque mean?

Back

Opaque materials do not allow any light to pass through, making it impossible to see through them.

Front

How does light travel?

Back

Light travels in straight lines.

Front

What causes light to bend when it enters a different medium?

Back

The change in speed of light causes it to bend.

Front

What happens to light when it hits a reflective surface?

Back

When light hits a reflective surface, it bounces back, a process known as reflection.
