Question
Verify that the equation $I=\langle u\rangle c$ is dimensionally consistent (i.e., check the units).
Step 1
Identify the units for each variable in the equation: - I: Intensity, measured in watts per square meter (W/m²) - ⟨u⟩: Mean energy density, measured in joules per cubic meter (J/m³) - c: Speed of light, measured in meters per second (m/s) Show more…
