Multiple choice general knowledge science & technology

Fans should not be mounted under tube light (ie)angle between fans and tube light should be perpendicular

  1. to avoid Flickering effect

  2. to get maximun coverage space

  3. to get more lighting

  4. Need not to be like that

A Correct answer
Explanation

When ceiling fans are mounted directly under tube lights, the rotating fan blades can cause the light to appear to flicker due to the stroboscopic effect, where the fan blades periodically block the light at a frequency that interacts with human vision. Mounting fans perpendicular to tube lights (at a 90-degree angle) prevents this visual annoyance. Options B, C, and D are incorrect: perpendicular mounting is not about coverage space, increasing light output, or being optional; it specifically addresses flickering.
