Waves Flashcards
(9 cards)
What is a description of a wave?
Waves are vibrations that spread out from the source.
What is amplitude?
Amplitude is the size of the vibrations. The higher the amplitude the larger the waves.
What is frequency?
Frequency is the speed of the vibration. The higher the frequency the faster the waves.
What does luminous mean?
A luminous object is something that emits light.
What does non-luminous mean?
A non-luminous object is something that does not emit light and often reflect it.
What happens when waves travel?
When waves travel from the source, the distance between the vibrations get wider and weaker.
What do waves do once they vibrate?
The waves will move but they will always return to there original place.
What does a traverse wave mean?
A traverse wave means the vibration of particles are perpendicular to the direction of the wave.
What is a definition of light waves?
Light waves are traverse waves, an electromagnetic wave by which light travels through a medium or vacuum.
