Period = total time/# of cycles
Unit: seconds

Frequency: How many cycles occur in one second
frequency = # of cycles/total time
Unit: cycles/second or Hz

How they are related:
Inversely proportional

Relationship to wave speed: Direct
Why does it affect wave speed the way it does: The higher the elasticity, the more quickly an object wants to return to its original shape]]> 2018-05-20 22:36:23 UTC https://padlet.com/anthony_cerqua/apirdj05pqz4/wish/262218806 anthony_cerqua https://padlet.com/anthony_cerqua/apirdj05pqz4/wish/262218898 Meaning: Mass per volume
Relationship to wave speed: Inverse
Why does it affect wave speed the way it does: The more mass the wave has to move through, the longer it will take]]> 2018-05-20 22:37:29 UTC https://padlet.com/anthony_cerqua/apirdj05pqz4/wish/262218898 anthony_cerqua https://padlet.com/anthony_cerqua/apirdj05pqz4/wish/262218949 Meaning: A measure of the amount of energy particles have
Relationship to wave speed: Direct
Why does it affect wave speed the way it does: Higher temp means faster moving particles. Also, higher temp means lower density (which means higher wave speed)]]> 2018-05-20 22:38:33 UTC https://padlet.com/anthony_cerqua/apirdj05pqz4/wish/262218949
