Common questions

What is the Wave Intensity formula?

Wave Intensity is written I = P/A. Energy transmitted per unit area per unit time. It belongs to Waves, under Wave Properties.

What are the units in I = P/A?

In SI units, I is intensity, measured in kg/s³; P is power, measured in kg·m²/s³; A is area, measured in m².

How is the Wave Intensity formula derived?

I = P/A by definition. The result is I = P/A.
