Ch 6: 4.8.19 Daily Quiz material Flashcards
which phase of matter?
- particles are linked in place
- has definite size
- has definite shape
- keeps its shape in a container
solid
which phase of matter?
- particles “slip and slide”
- has definite size
- has no definite shape
- takes the shape of a container
liquid
which phase of matter?
- particles move independently
- have no definite size
- have no definite shape
- completely fills a container
gas
phase of matter which is a “soup” of charged particles
example: the sun
plasma
the propogation of energy through a medium
wave
a wave where the particles of the medium move perpendicular to the direction of the wave
examples: flags flying, crowds doing “the wave” at sporting events
transverse wave
a wave where the particles of the medium move parallel to the direction of the wave
longitudinal wave
the distance required to complete one cycle (from peak to peak, or valley to valley)
wavelength
the time required to complete one cycle
period
T
the number of cycles per second
frequency
the maximum distance from the mid-line
amplitude
amplitude modulation (radio)
AM
frequency modulation (radio)
FM
ocean waves are a combination of…?
transverse and longitudinal waves
the unit for frequency is:
Hertz (Hz)
equation: frequency
frequency is one over period
equation: wave velocity
wave velocity is wavelength over period -or- wavelength times frequency
note: always include direction of a.f.s. (away from source) in answer
