5.1 Waves Flashcards
What is amplitude
The distance from the middle to the top of the wave
What is Frequency
Number of waves/oscillations per second
what is wavelength
Distance from one point of a wave to the same point on the next wave
what is time period
the time for one wave to pass a point
What is the difference in transverse and longitudinal waves
sound waves are longitudinal and their direction of vibration is the same direction as the waves. In transverse waves the direction of vibration is at right angles to the direction of the travel of the wave.
How do you model waves?
Ripples on water waves model transverse waves. If u place a small object you can tell the wave travels and not the water,
What happens when a wave travels between mediums?
The velocity and direction may change but a refraction occurs
What happens to the wavelength of a sound wave when it moves between mediums?
It will move away from a line at 90 degrees to the surface which increases the wavelength of the soundwave.
what can happens to a sound wave at a boundary?
it can be reflected (echo), transmitted or absorbed
What happens to frequency of a sound wave when it moves between mediums?
stays the same
