Question

lightning is seen first while sound is heard later. Explain​

Answer 1

Answer:

because light travels faster than sound

Light doesn't need a medium to travel. The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second.

Answer 2

We hear sound of lightening after it is seen because Light travels faster than Sound.

Therefore, Lightning's light reaches to our eyes much before it's sound.
