Wave Intensity from Amplitude
I = 0.5·ρ·v·ω^2·A^2
What it says
The power a mechanical wave carries per unit area, which grows as the square of its amplitude.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
I | Intensity (W/m^2) | M T^-3 |
ρ | Medium density (kg/m^3) | M L^-3 |
v | Wave speed (m/s) | L T^-1 |
ω | Angular frequency (rad/s) | T^-1 |
A | Amplitude (m) | L |
