Light Energy Flashcard TEKS 5.8C

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one material to another, caused by a change in its speed.

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 does not pass through or reflect.

Front

What is transmission of light?

Back

Transmission is the passing of light through a material without being absorbed.

Front

How does a magnifying glass work?

Back

A magnifying glass works by refracting light to enlarge the image of an object.

Front

What happens to light when it passes through a prism?

Back

Light bends (is refracted) as it passes through a prism, separating it into different colors.

Front

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

Back

The straw looks bent because light rays are refracted when they travel from water to air.

Front

What is an example of refraction in nature?

Back

An example of refraction in nature is light bending as it passes through a raindrop, creating a rainbow.

Front

What is the difference between refraction and reflection?

Back

Refraction involves bending of light as it passes through materials, while reflection involves light bouncing off surfaces.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.
