Waves Flashcards
What is a medium?
Matter the waves travel through
What is a wave?
Disturbance that carry energy
What is frecuency?
Amount of waves in a sec
In wich types are divides the waves with médium?
2 tranverse and longitudinal
What is a period?
Time it takes one wave to pass
Which is the fórmula to calculate the waves speed?
Speed: frecuency x wavelenght
On what depends the waves speed?
Depends on the medium
Wínch is the crest?
Is the highest point on the wave
Wich is the amplitude?
The space between the Middle to the bottom of to the top
Which are the parts of a tranverse waves?
Amplitude, trough, wavelenght, crest and complete cycle.
How can waves be?
With medium or with no medium.
In what is measured frecuency?
In hertz / hz
In what is measured wavelenght?
In Landa/ meters
In what is measured speed?
In m/s
Wich are the waves behavior ?
Reflection
Refraction
Diffraction
How reflection works?
The bouncing back of a wave after it strinks a barrier
Wich are examples of reflection?
Eco,sound, mirror
How works refraction?
Its the bending of a wave as it enters to a new medium at an angle other than 90
Why refraction occurs?
Because waves travel at different speed a at different meduims./ And when one side of the wave slows or speed up it cause the wave to bend.
How diffraction works?
The spreading of waves through an opening or a round The edge of an obstacle.
