Pitch & Loudness
100

Light travels in straight lines until it interacts with something.

What is how light normally travels?

100

Materials that let some light pass through.

What are translucent materials?

100

The distance between one crest and the next.
 

What is wavelength?

100

A type of wave that requires matter to travel.
 

What is a mechanical wave?

100

This part of a wave controls loudness.
 

 What is amplitude?

200

The bouncing of light off a surface.

What is reflection?

200

Materials that block all light.

What are opaque materials?

200

The height of a wave from its resting position.
 

What is amplitude?

200

Sound is created by this.
 

 What are vibrations?

200

This part of a wave controls pitch.
 

What is frequency?

300

The bending of light when it moves between materials.

What is refraction?

300

Wax paper is an example of this type of material.

What is translucent?

300

A wave with more space between crests has this.
 

 What is a greater (longer) wavelength?

300

Sound cannot travel through this.
 

What is empty space (a vacuum)?

300

Higher amplitude means this.
 

What is louder sound?

400

This type of surface reflects the most light.

What are smooth, shiny, light-colored surfaces?

400

Wood and metal are examples of this type of material.

What is opaque?

400

Moving your hand more while shaking a rope increases this.
 

 What is amplitude?

400

Sound travels fastest in this state of matter.
 

What are solids?

400

Higher frequency means this.
 

What is higher pitch?

500

A pencil looking broken in water is caused by this.

What is refraction?

500

This describes how light moves through different materials.

What are material interactions?

500

The line in the middle of a wave that represents no movement.
 

What is the rest position?

500

Two factors that affect the speed of sound.
 

What are temperature and density?

500

A bass drum produces this type of frequency.
 

What is low frequency?
