Q. Scientists used which entity to change the direction of lightning strikes for the first time?
Answer:
Laser
Notes: Scientists used a high-powered laser to change the direction of lightning strikes for the first time. The laser was aimed at the sky on the top of Mount Santis in north-eastern Switzerland.
The new device, called Laser Lightning Rod (LLR), could increase protection by extending the height of rods hundreds of meters. With more development, LLR could improve protection for important places such as power stations and airports.
