The Basics
A(n) _______________ is a disturbance that transfers energy from place to place.
What is a wave?
Waves are generated when a source of ____________ forces the matter in a medium to vibrate.
What is energy?
T or F: Moving your hand back-and-forth to "wave" at someone is generating energy to create waves.
What is true?
Transverse waves move the medium at _____________ to the direction the waves are traveling.
What are right angles?
Energy is the ability to do ____________.
What is work?
A(n) ________________ is a repeated back-and-forth or up-and-down motion.
What is a vibration?
These are the two types of mechanical waves.
What are transverse and longitudinal?
Sound waves travel through a ________.
In ______________ waves, particles in the medium are moving parallel to the direction the wave is traveling.
What are longitudinal waves?
Mechanical waves only travel through a medium such as _________, _____________, or _____________.
What is a solid, liquid, or gas?
These types of waves do not require a medium and can travel through empty space.
What are electromagnetic waves?
The ___________ is where the displacement of wave is at a maximum.
What is the crest?
Across is another word for ________________.
What is transverse?
In longitudinal waves, _________________ is when the particles in the medium are close together and _______________ is when the particles are spread apart.
What is compression and rarefaction?
Frequency refers to the number of _____________ per second.
What are vibrations?
The _________________ is where the medium shows no disturbance.
What is the rest position?
The ________________ of a wave is the vertical distance between a peak (crest) and rest position or between a valley (trough) and rest position.
What is the amplitude?
The frequency formula for a wave is ________________.
What is speed divided by wavelength?
Amplitude is measured based level of compression or rarefaction in a(n) ___________________ wave.
What is a longitudinal wave?
The _____________ is where displacement of the medium is at a minimum.
What is the trough?
Measuring from crest to trough in a transverse wave is an example of wavelength. T or F
What is false?
Frequency is measured in units called ___________.
What are hertz?
In longitudinal waves, the particles of/in the medium move ______________ in the same direction the wave is traveling.
What is back-and-forth?
Amplitude is measured between peak and rest position or valley and rest position in a(n) _____________ wave.
What is a transverse wave?
In transverse waves, the particles of/in the medium move __________________ to the direction of the way, or across it.
What is perpendicular?
