Answer 2

Question:

We see flash earlier than thunder . Explain ?

Answer:

We see flash earlier than thunder because the speed of light is more than the speed of sound . Sound is slower , it takes some more time than light to reach us . This is why we see flash earlier than thunder sound .

• Speed of sound - 330m / s at O degrees celsius.

• Speed of light- 3 * 10 ^ 5 km / s.
