MCQ
Convex lens is not used in:
- ASimple microscope
- BSpectacles
- CTelescope
- ✓Flood lights
✓
Answer
Correct option: D.
Flood lights
Convex lens always converges the parallel rays but in flood lights, we want to diverge the incident rays so as to light up more area. Thus we use a diverging lens i.e. a concave lens. Thus a convex lens is not used in flood lights.
