physics- intro Flashcards
a wave is…..
a disturbance that transfers energy from one point to another without transferring matter.
the highest point in the wave
crest
lowest point in the wave
trough
rest position
level of water where there are no waves
wave length
the distance from 1 point of the wave to the next same point on the wave (Eg: crest to crest)
symbol for wavelength
greek letter lambda
wavelength is measure in
meters
amplitude
it is the wave height from the rest position of the wave to the crest or the wave depth from the rest position to the trough
rate of repetition of the wave
frequency
the standard symbol for frequency
f
frequency is measured in
hertz, which cycles per second
the _________ the amplitude, the more energy is carried. and vice versa
larger
light is
a form of energy
visible light
is only a tiny fraction of the energy that surrounds us everyday
___________ is a pattern made of electric and magnetic fields that can travel through empty space
electromagnetic radiation.
the electromagnetic spectrum is the entire range of electromagnetic radiation extending from the ___________ to _________ waves
shortest to longest
when sun/ white light is shone through a prism, the light separates into the________
colors of the rainbow, which are ROYGBV
the range of different colors of light is called the
visible spectrum
the colors of the spectrum can be explained using the ___________
wave model
if wave crest pass the dock 10 times in a minute, the frequency of the wave is
10 cycles /minute
