Flashcards in Waves Deck (24)
What are waves?
Periodic disturbances in a medium
T/F: A wave transfers energy and material
False. A wave transfers energy without transferring the material.
Any material a wave can move through
What are common mediums?
T/G: Waves move the medium through which they travel.
False. Waves disturb the medium, they do not move it.
What is the most common form of a wave?
Type of wave where the motion of the medium is perpendicular to the direction of the wave
Type of wave where the motion of the medium is along the direction of the wave speed
What type of wave is sound?
People pushing one another forward in a line is an example of what type of wave?
Spots along the nodal line are called what?
The points above and below the equilibrium
Measurement of the energy in a wave
The length of a wave
The number of waves passing a point in one second
Frequency is measured in what units?
Frequency is the inverse of ________________.
The time for one wave cycle to complete
Symbol for Wavelength
Audible human range for frequency
Equation for wave speed
Speed of Sound
340 m/sec in air (at 20 degrees celcius)
1520 m/sec in steel
T/F: The speed of a wave has nothing to do with its frequency or wavelength.
True. The speed of a wave is determined only by the medium through which it is traveling.
