- flicker
- glare
- excessive brightness
- excessive contrast
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Lighting quality in interior environments is defined not only by illumination levels but also by the stability of the light source.
Step 2: Detailed Explanation:
- Stroboscopic Effect: This is a visual phenomenon that occurs when moving or rotating machinery appears to be stationary, slow-moving, or moving in reverse under a periodic light source.
- Cause: It is directly caused by the rapid, periodic modulation of light output, known as flicker, which is common in low-frequency fluorescent tubes or low-quality LED lamps operated on alternating current (AC).
- Other Terms:
- Glare: Visual discomfort caused by excessive luminance differences in the field of view.
- Excessive brightness/contrast: Can cause eye strain and glare but do not create stroboscopic illusions.
Step 3: Final Answer
The stroboscopic effect in interiors occurs due to light flicker.
