Waves Basics
This is the distance from one crest to next.
What is wavelength?
The highest point of a transverse wave.
What is a crest?
Sound waves are this type of wave.
What are longitudinal waves?
This happens when a wave bounces off a surface.
What is reflection?
A wave has a frequency of 5 Hz and a wavelength of 2 m. What is its speed?
What is 10 m/s?
Waves carry this but do not transfer matter.
What is energy?
The lowest point of a transverse wave.
What is a trough?
This determines how high or low a sound is.
What is frequency or pitch?
When waves bend around corners or spread out through openings.
What is diffraction?
A wave moves at 20 m/s and has a wavelength of 4 m. What is its frequency?
What is 5 Hz?
A wave that needs a medium(like air or water) to travel.
What is a mechanical wave?
If frequency increases, this must decrease.(Assuming wave speed stays constant).
What is wavelength?
This determines how loud a sound is.
What is amplitude?
When two waves meet and combine.
What is interference?
A sound wave travels at 340 m/s and has a frequency of 170 Hz. What is its wavelength?
What is 2 m?
The two main types of waves.
What are transverse and compressional waves?
The amount of energy in a wave is related to this property.
What is amplitude?
Sound travels fastest in this state of matter.
What is a solid?
Waves that line up crest-to-crest creates this type of interference.
What is constructive interference?
What is decreasing it?
The number of waves that pass a point in one second.
What is frequency?
The formula that connects speed, frequency, and wavelength.
What is v= fλ?
The science term for when a moving object changes the pitch of a sound you hear.
What is the Doppler Effect?
A pattern formed from waves reflecting and interfering, often seen on strings.
What is a standing wave?
A wave has a period of 0.25 seconds. What is its frequency?
What is 4 Hz? (since f= 1/T)
