Waves Sound and Light Flashcards
Where are waves
everywhere
What are sounds
Change of air pressure
What are all waves formed by w/ the exception of light waves
Medium disturbed by a force
What are quanta
energy packets
What are waves formed by a medium called
mechanical waves
What is frequency
numbers of cycles in one second
What is an oscillation
something going up and down or back and forth
What is the SI unit of frequency
Hertz
How can you tell how big an oscillation is
with a m p li tu de
What does amplitude measure
Amount of energy a wave is carrying
What does a frequency measure
the number of oscillations cycles wave completely in a second
What is wavelength
The spatial separation between the peaks of the waves
What is a wave?
A disturbance in space and time that carries energy
What is a Transverse wave
Waves formed when the source of the wave is oscillating in a direction perpendicular to the direction the wave propagates
What are longitudinal waves
When waves are oscillating in a direction parallel to the direction of wave propagation
