What are waves that require a medium through which to travel called?
What are mechanical waves?
100
What is the distance between 2 corresponding parts of a wave called?
What is the wavelength?
100

When two or more waves interfere creating a wave with a higher amplitude.

What is interference. 

100

Theaters often use curtains to help with sound quality. When sound waves hit the curtains, the curtains take some of the energy. This interaction is called

What is absorption.

100
Sound travels through a medium as what kind of wave?
What is a longitudinal wave?
200

The highest point on a transverse wave.

What is a crest.

200
What is the number of waves that pass a given point in a given amount of time?
What is frequency?
200

The bending of a wave as it passes at an angle from one medium to another; caused by the wave changing speed.

What is refraction?

200

What is the wave interference that causes the following: When band members play the same note, resulting in a louder sound.

What is constructive interference.

200

The loudness of sound waves is measured in this unit. 

What is a decibel. 

300

The lowest point on a transverse wave.

What is a trough.

300
What is the unit of measurement of frequency?
What is a hertz?
300
What occurs when two waves combine to form a wave with a smaller amplitude?
What is destructive interference?
300

What is the wave interaction that causes an echo.

What is a reflection.

300

These sound waves are at very high frequencies that humans cannot hear.  They are used in medical devices.  

What is ultrasound.

400

The height of a transverse wave. 

What is amplitude. 

400
What is the mathematical formula used to calculate the speed of a wave?
What is speed = wavelength x frequency?
400
What occurs when external vibrations match an object's natural frequency?
What is resonance?
400

You can hear your friend in the hallway before they come into class. This is an example of which wave interaction?_______, the change in direction of a wave when the wave encounters an obstacle or edge.

What is diffraction.

400

When a plane flies faster than the speed of sound, it is called

What is breaking the sound barrier or a sonic boom.

500

These wave vibrate in the same plane as the direction of the energy.  They are sometimes called compression waves. 

What is a longitudinal wave. 

500
What is the frequency of a wave with a speed of 3m/s and a wavelenght of 0.2m?
What is 15 Hz?
500

This type of wave is the result of reflection and interference. Although its amplitude may change, it appears to not move.

What is a standing wave.

500

SONAR uses which type of wave interaction?

What is reflection.

500
As a sound travels toward you, like a siren, you notice that its pitch changes.
What is the Doppler Effect?
