c. Light has more velocity than sound that of sound wave
d. None other
Choose the correct ans..

Answer 1

Answer:

We always see the lightning first before the thundering sound because

(c) Light has more velocity than sound

Explanation:

Light waves have a velocity of 3 × 10^8 m/s whereas sound waves have a velocity of 330 m/s in air and so it can be clearly stated that light waves travel faster than sound waves in air. Therefore, lightning is seen before the sound of thunder as it reaches us faster.

Answer 2

Answer:

Light waves have a speed of 3 × 10^8 m/s while sound waves have a speed of 330 m/s in air thus it very well may be obviously expressed that light waves travel quicker than sound waves in air.

The We generally observe the lightning first before the roaring stable since Light has more speed than soundrefore, lightning is seen before the sound of roar as it contacts us quicker.
