Mr. M's OpenSciEd Unit 1 Review Light & Matter

Front

What is Refraction?

Back

Refraction is the bending of light waves when they pass from one medium to another, causing a change in speed and direction.

Front

What happens during Reflection?

Back

Reflection occurs when a light wave bounces back from a surface that it cannot pass through.

Front

What is Absorption in terms of light?

Back

Absorption is when light waves are taken in by a material and do not pass through or reflect.

Front

What does it mean for an object to be Opaque?

Back

An opaque object does not allow light to pass through it, making it impossible to see through.

Front

Why do we see objects more clearly when they reflect more light?

Back

We see objects more clearly when they reflect more light because more light enters our eyes, allowing our brain to process a clearer image.

Front

What is the difference between Reflection and Refraction?

Back

Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it passes through different media.

Front

What is a Translucent object?

Back

A translucent object allows some light to pass through but scatters it, making objects behind it appear blurry.

Front

How does distance affect the clarity of an object we see?

Back

The closer an object is, the more light enters our eyes from it, making it appear clearer than objects that are farther away.

Front

What is the role of light in seeing objects?

Back

Light reflects off objects and enters our eyes, allowing us to see and identify them.

Front

What is the significance of light intensity in visibility?

Back

Higher light intensity means more light is available to enter our eyes, improving visibility and clarity of objects.
