Radiant intensity measures the amount of radiant energy emitted by a source in a specific direction per unit solid angle. It is essential in fields such as optics, astronomy, and radiometry, where understanding energy distribution and propagation is necessary.
Example Conversions:
- 1 watt per steradian = 1 radiant intensity unit
- 100 lumens ≈ 100 watts per steradian (for specific light sources)
