When two or more waves interfere creating a wave with a higher amplitude.
What is interference.
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.
The highest point on a transverse wave.
What is a crest.
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?
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.
The loudness of sound waves is measured in this unit.
What is a decibel.
The lowest point on a transverse wave.
What is a trough.
What is the wave interaction that causes an echo.
What is a reflection.
These sound waves are at very high frequencies that humans cannot hear. They are used in medical devices.
What is ultrasound.
The height of a transverse wave.
What is amplitude.
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.
When a plane flies faster than the speed of sound, it is called
What is breaking the sound barrier or a sonic boom.
These wave vibrate in the same plane as the direction of the energy. They are sometimes called compression waves.
What is a longitudinal wave.
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.
SONAR uses which type of wave interaction?
What is reflection.
