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

Front

What is reflection in terms of light?

Back

Reflection is when a light wave bounces back from a surface that it cannot pass 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 brains to process the image better.

Front

What happens to light when it hits a translucent object?

Back

Light can pass through a translucent object, but it is scattered, making the object appear blurry.

Front

What is the path of light that allows us to see a reflection?

Back

The path of light that allows us to see a reflection is when light from a source (like the sun) reflects off an object and then reflects off a surface (like glass) into our eyes.

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 from one medium to another.

Front

What is the role of light in seeing objects?

Back

Light is essential for seeing objects because it illuminates them, allowing our eyes to detect and our brains to interpret the images.

Front

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

Back

The closer an object is, the more light it reflects into our eyes, making it appear clearer compared to objects that are farther away.

Front

What is absorption in terms of light?

Back

Absorption is when light is taken in by an object and does not reflect or transmit through it.

Front

What is an example of a translucent object?

Back

Frosted glass is an example of a translucent object, as it allows some light to pass through but scatters it.

Front

What is the definition of a light wave?

Back

A light wave is a type of electromagnetic wave that is visible to the human eye.
