waves Flashcards
(12 cards)
what is a wave
a wave is something that transfers energy from one point to another
what is a transverse wave
a wave that moves in a direction at right angles to the way in which the particles are vibrating
what is a longitudinal wave
a wave that moves in the same direction as the direction in which the particles are vibrating
are all waves in the elctromagnetic spectrum transverce including water waves
ye
is sound a longitudnal wave
yes
what is wavelength
the distance from a point where the wave begins to repeat its self
what is frequency and what’s it measured in
frequency is how many waves produced in 1 second measured in hertz
what is amplitude and whats it measured in
the amplitude of a wave is half the distance from peak to trough also thought of as the height of the wave and its measure in meters
what is wave speed
the wave speed is how quickly it travels from its source
what is period
the period of the wave is the time taken for one complete wave to be produced
what is the wave eqausion
v=f x lamda
what is diffraction
the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge,
