Waves Flashcards
(12 cards)
What is a disturbance or series of vibrations that travels from one place to another?
A Wave
It carries energy with or without medium.
It is a substance or material through which a wave travels.
Medium
Example: water, air, solid
Type of wave: vibrations of particles are perpendicular to the direction of travel
Transverse Wave
A form of mechanical wave.
Type of wave: vibrations of particles are parallel to the direction of travel
Longitudinal Wave
A form of mechanical wave.
Type of wave: vibrations of particles undergo a circular motion
Surface Wave
A form of mechanical wave.
A transverse wave that DOES NOT NEED matter (a medium) to transfer energy
Electromagnetic Wave
Parts of a Wave: The peak or the highest point of a wave
Crest
Parts of a Wave: The undisturbed position of the particles if they do not vibrate
Rest or Equilibrium Position
Parts of a Wave: The lowest point of a wave
Trough
Parts of a Wave: It is the maximum disturbance from the crest of the wave from its rest position. It represents the wave’s height.
Amplitude
The unit for amplitude (A) is meters (m).
Parts of a wave: It is a set distance that represents the full cycle of a wave. It can be measured from crest to crest, from trough to trough, or any two consecutive points in the wave cycle.
Wavelength
The unit for wavelength (λ, Greek letter lambda) is meters (m).
Parts of a Wave: It is the number of waves passing a specific point per second.
Frequency
