Light- Reflection and Refraction Practice Flashcard

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air to water.

Front

What happens to light when it passes through water?

Back

Light bends when it passes through water, causing objects like a pencil to appear broken.

Front

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

Back

The straw appears bent because light is refracted as it moves from water to air.

Front

What is reflection?

Back

Reflection is when light hits a surface and bounces back.

Front

What is created when light hits a solid or opaque barrier?

Back

A shadow is created when light hits a solid or opaque barrier.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different mediums.

Front

What is an example of refraction in everyday life?

Back

An example of refraction is seeing a straw in a glass of water that looks bent.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What is an opaque object?

Back

An opaque object is one that does not allow light to pass through, creating a shadow.

Front

What is a transparent object?

Back

A transparent object is one that allows light to pass through without significant scattering, like clear glass.
