In SI units, the unit of Candela is used for the measurement of:
Correct answer: B. Light intensity
- A. Heat intensity
- B. Light intensity
- C. Energy/time
- D. Energy/area
Explanation
The Candela is specifically a unit for measuring luminous intensity, which is the amount of light emitted in a particular direction. This measurement takes into account the sensitivity of the human eye to different wavelengths of light. Luminous intensity is important in applications where the visual perception of light is crucial, such as lighting design, optics, and photometry.
