Question

In a thunderstorm the thunder is made at the same time as the lightning . Explain why a person 1600 metres away hears thunder about 5 seconds after seeing the lightning .

Answer 1

Answer:

This is because speed of sound in air is less than speed of light.

Explanation:

Here we know that speed of sound in air is around 330m/s and light is 3×10^8m/s.So the light of the thunder comes first not the sound.

Answer 2

The speed of light is 3,00,000 KMPS

The speed of sound is about 300 MPS

see ,

speed of sound × Time

300×5

=1500M
