Wave Properties
All waves carry ______________.
What is energy?
The harmonic number of a standing wave is the same as the number of __________________ in the standing wave.
What are antinodes?
What do you hear when two waves of slightly different frequency are played together?
What are beats?
The way in which interference patterns are produced.
What is superposition?
The points of destructive interference in a standing wave are called ________________.
What are nodes?
A conductor hears a beat frequency of 3 Hz between two tubas; one tuba is playing a frequency of 152 Hz. What frequency is the other tuba playing?
What is 155 Hz or 149 Hz?
The medium particles move back & forth (oscillated) perpendicular to direction of wave.
What is a transverse wave?
If the fundamental frequency of a standing wave is 13 Hz, then the frequency of the 4th harmonic will be ________________.
What is 52 Hz?
Human beings can hear frequencies between the range of 20 Hz up to __________________.
What is 20,000 Hz?
If you are riding in a train and the conductor pulls the horn; what tone will you hear?
What is a constant tone?
Waves travel at a frequency of 4.0 Hz. Therefore, their period must be________
What is 0.25 s?
If the distance between the boundaries is 7m, then the wavelength of the 4th harmonic of a standing wave is ____________.
What is 3.5 m?
The "pitch" of sound refers to a sound wave's ____________.
What is frequency?
What can change the speed of a wave?
What is change in medium?
What can be plotted on the x-axis of a wave graph?
What are time (s) and distance (m)?
A building sways back and forth every 10 seconds. Therefore the frequency of its vibrations is _____.
What is 0.1 HZ?
If the 5th harmonic frequency of a standing wave is 120 Hz, then the fundamental frequency is __________________.
What is 24 Hz?
Sound requires a medium to propagate through. Therefore it is considered to be a ______________ wave.
What is mechanical?
In which medium will a wave travel faster, water or air and why?
What is water, the more dense a medium the faster the wave will travel. Water is more dense than air therefore the wave will travel faster in water.
