Light: Refraction, Reflection, and Absorption

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing it to change speed.

Front

What does it mean if a material is transparent?

Back

A transparent material allows all light to pass through it without scattering, making objects behind it clearly visible.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

What is absorption in terms of light?

Back

Absorption is when light is taken in by a material and not reflected or transmitted.

Front

What is a shadow?

Back

A shadow is formed when an object blocks the path of light.

Front

What does translucent mean?

Back

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

Front

Why does a straw appear bent in a glass of water?

Back

The straw appears bent due to the refraction of light as it passes from air into water.

Front

What happens to light when it hits a black surface?

Back

A black surface absorbs most of the light that hits it, making it hotter than lighter surfaces.

Front

What is the difference between opaque and transparent materials?

Back

Opaque materials do not allow any light to pass through, while transparent materials allow all light to pass.

Front

How does light behave when it hits a mirror?

Back

Light reflects off a mirror, allowing us to see our image.
