When someone returns from a heavy metal concert they don’t usually comment loudly about how many Watts per meter squared they experienced. Decibels might make sense. People tend to know that 120 …
Wave Interaction, Beats, Destructive Interference
When waves come into contact with each other they can interact together to increase or decrease amplitude. If two sound waves are slightly off in frequency you can hear the peaks where the waves add …

Wave Mediums, Bulk Modulus
Waves must be distinguished as to what medium they are traveling through, if you want to make any sense of data. Sound will travel at a certain rate in air and another in water, and these rates can …
Vectors, components, sine and cosine in power series
Back in algebra II or so you probably started going over vectors. To start off, you could describe a vector using an angle (like that on a compass) and a magnitude or as two components (i and …

Tranverse and Longitudinal Waves
Waves exist in two forms– transverse (like an ocean wave) and longitudinal (like sound waves). A transverse wave has a displacement perpendicular to the medium while the displacement of the medium …
Physics of White Water Rafting Bernoulli Pressure
If you go ever go white water rafting you’ll start out in a nice calm area, kind of like the happy singing place on Splash Mountain in Disneyland. The river is wide at this point and the velocity of …
