Detailed Solution
Download Solution PDFThe correct answer is option 2):(distribution of luminous intensity of light source in all directions)
Concept:
- The polar curves represent the distribution of light or luminous intensity of a light source in all directions or over the surrounding surface.
- The polar curves are drawn by taking luminous intensities in all directions at an equal angular displacement
- If the luminous intensity is measured in a horizontal plane about a vertical axis and a curve is plotted between the candle power and the angular position, a curve known as Horizontal Polar Curve is obtained as shown below.
- If the luminous intensity is measured at the angular position in a vertical plane, a polar curve in the vertical plane called a Vertical Polar Curve is obtained as shown below.
