Unit 5: Waves Assessment

Front

What is a translucent object?

Back

A translucent object allows some light to pass through but not enough to see clearly through it, such as a foggy shower door.

Front

Why does an apple appear red?

Back

An apple appears red because it reflects red light and absorbs all other colors.

Front

In which medium do sound waves travel the fastest?

Back

Sound waves travel fastest in solids because the particles are closer together, allowing for quicker transmission of sound.

Front

What are the primary colors of light?

Back

The primary colors of light are red, green, and blue.

Front

What type of light does the sun emit?

Back

The sun emits white light, which contains all colors of the visible spectrum.

Front

Define opaque.

Back

An opaque object does not allow any light to pass through it, meaning you cannot see through it.

Front

What is refraction?

Back

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

Front

What is the difference between reflection and absorption of light?

Back

Reflection is when light bounces off an object, while absorption is when light is taken in by an object.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another, often through a medium.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.
