Wave Fundamentals
This is defined as a disturbance that carries energy through matter or space.
What is a wave?
This wave property determines the pitch of a sound.
What is frequency?
This occurs when two waves combine to form a wave with greater amplitude.
Constructive Interference
Sound travels fastest in this state of matter.
Solids
This is the formula used to calculate wave speed.
v = fλ
As wavelength of wave decreases, the frequency will
What is increase?
This wave property determines the loudness of a sound.
What is amplitude?
This occurs when two waves combine and cancel each other out.
Destructive Interference
Sound travels faster in solids because of this property of their particles.
Particles are closer together and transfer vibrations faster?
A wave has a frequency of 60 Hz and a wavelength of 5 m. Calculate its speed.
300 m/s
These waves require a medium to travel, unlike electromagnetic waves which do not.
What is mechanical waves?
When two waves moving in opposite directions produce a standing wave.
What is resonance?
How can the doppler effect tell the direction an object is moving?
What is moving in the direction of the higher frequency?
A period of 2 secs corresponds to the frequency.
What is 0.5 sec?
A wave has a frequency of 8 Hz and a speed of 32 m/s. Calculate its wavelength.
4 meters
This is an example of a mechanical wave that requires a medium to travel.
What is a sound wave?
The Doppler Effect occurs when there is this between the source and the observer.
What is motion between the source and the observer.
Shattering a glass using high-pitched sound happens because of this?
What is resonance?
A frequency of 512 Hz corresponds to a period of?
What is 0.0019?
A wave has a wavelength of 15 m and a speed of 450 m/s. Calculate its frequency.
30 Hz
As the frequency of a wave increases, the period of the wave will
What is decrease?
What is the mathematical relationship between frequency and period.
What is an inverse relationship?
Sound waves reflecting off a hard surface and returning to the listener.
What is an echo?
Greater amplitude means greater ______________
Shorter wavelength means ____________________
What is energy?
What is higher frequency?
A wave has a period of 0.02 s and a wavelength of 6.84 m. Calculate its speed.
342 m/s
