Wave basics Flashcards
What is the amplitude of a wave
The displacement from the rest position to the crest.
What is the wavelength of a wave
The length of a full cycle of the wave
From crest to crest
What is the crest of the wave
Where the wave curves
What is the frequency of a wave
The number of complete waves passing a certain point per second OR the number of waves produces by a source per seconds
What are 4 examples of transverse waves
Light or all other EM waves
Ripples on the water
Waves on strings
A slinky spring when you wiggle it up or down
What is particular about transverse waves
The wave vibrations are perpendicular (at 90 degrees) to the direction of energy transfer of the wave
What direction do vibrations of transverse waves go
Side to Side
What are 3 examples of longitudinal waves
Sound waves and ultrasound
Shock waves
A slinky spring when you pull the end
What is particular about longitudinal waves
The vibrations are parallel to the direction of energy transfer from the wave
What waves occur when you wiggle a slinky spring up or down
