Sound Waves Vocab
What is a Wavelength?
The distance from one point on the wave to the exact same point on the next wave.
Example: the first compression, rarefaction, to the 2nd compression, rarefaction
An elephant sounding off it's trumpet is an example of what amplitude?
High Amplitude.
What is
he bending and spreading of sound waves around obstacles or through narrow openings. Because sound waves—especially low-frequency tones—have long wavelengths, they can bend around corners or spread out after passing through a doorway, allowing you to hear sounds around a barrier even when direct line of sight is blocked.
Diffraction
Give an example of high Amplitude sound waves
a high volume sound
draw high amplitude sound waves
close together compressions super spread out rarefactions
what is compression?
The section of the wave that is squeezed together.
A bullhorn in an assembly sounding off is an example of what amplitude?
High Amplitude.
what is The process in which sound energy is taken in by a material rather than reflected or transmitted. Soft, porous, or flexible materials (such as acoustic foam, carpets, and heavy drapes) convert sound wave kinetic energy into small amounts of heat, reducing overall sound intensity in a room.
Absorption
give an example of low amplitude sound waves
low volume sound
draw low amplitude sound waves
not as close compressions and not as many and rarefractions not as spread out
what is rarefraction?
the section of the wave that is spread apart.
Someone whispering in class is an example of what amplitude?
low amplitude.
what is
The bouncing of sound waves off a surface back into the medium. When sound encounters a hard, dense, or smooth obstacle (such as concrete, glass, or stone), the wave energy bounces off at an angle equal to its angle of incidence, producing phenomena like echoes and reverberations.
Reflection
Give an example of high energy sound waves
something loud and with lots of energy, lots of force and vibrations
Draw high energy sound wave
lots of force lots of compressions super close together and super spread out rarefractions
what is diffraction?
when waves bend around obstacles. example talkig in the hall and your sound waves go through the doorway into the nearby classroom.
Mrs.Whitcomb singing Justin Bieber at the assembly is an example of what amplitude?
High Amplitude and AMAZING SINGING!
what is a bat searching for food?
Reflection and echolocation
give an example of low energy sound waves
low force, low energy and low vibrations and low volume
draw a low energy sound wave
less force, compressions not as many and not as close together and rarefractions not as spread out.
what is Reflection?
Reflection of sound waves is the bouncing of sound waves off a surface back into the medium. When sound encounters a hard, dense, or smooth obstacle (such as concrete, glass, or stone), the wave energy bounces off at an angle equal to its angle of incidence, producing phenomena like echoes and reverberations.
Someone tiptoeing into class late is an example of what amplitude?
low amplitude and good luck getting past Mrs.Whitcomb lol
what is Justin Bieber recording in a sound booth?
Absorption
explain a sound wave that you heard today was it low amplitude or high amplitude explain using vocab in your answer!!
Mrs.whitcomb will decide if your answer is correct
What is a good 4 answer to explain what is happening in a sound wave when Mrs.Whitcomb is talking and students are also talking at the same time
Mrs. Whitcomb will check that all sound waves are bouncing off and being reflected, diffracted and absorbed depending on the material around us and there are so many sound waves in the room!
