What is a wave? - ---ASNWERS----a disturbance that moves through matter or space
What is a vibration? - ---ASNWERS----A repeated back-and-forth or up-and-down motion
What is a medium? - ---ASNWERS----It is the material through
which a wave travels (solids, liquids or gasses)
Types of waves - ---ASNWERS----Transversal, compressional/longitudinal, and electromagnetic
Transversal wave - ---ASNWERS----A mechanical wave where particles of matter move back and forth at
right angles
Crests - ---ASNWERS----high points on a wave
Troughs - ---ASNWERS----The low points on a wave
Direction of rope - ---ASNWERS----the rope moves up and down
Direction of wave - ---ASNWERS----the wave moves away from its source of origin
, Crests and Troughs travel ______ the rope - ---ASNWERS----along
The particles in the rope only move _____ and _____ - ---ASNWERS----up and down
compressional wave - ---ASNWERS----Mechanical wave where, a wave in which matter moves back and
forth in the direction the wave is moving
Compression - ---ASNWERS----where the coils are are squeezed together
Rarefaction - ---ASNWERS----where the coils are spread apart
Electromagnetic wave - ---ASNWERS----transverse wave that electric and magnetic parts move
perpendicular to the direction of the wave
What are the properties of waves? - ---ASNWERS----wavelength, frequency, amplitude, energy, and
speed
Calculating wavelength - ---ASNWERS----the distance between one point on a wave and the nearest
point, waves must be of the same speed and direction
transverse wavelength - ---ASNWERS----measurement crest to crest or trough to trough
compressional wavelength - ---ASNWERS----measurement compression to compression or rarefaction to
rarefaction
frequency - ---ASNWERS----the number of complete wavelengths that pass a point each second
frequency mathematical formula - ---ASNWERS----f=#h/s
