as a thunderstorm approaches, lightning may be seen, then thunder may be heard several seconds later. this phenomenon occurs because —\na storm clouds have less pressure than the surrounding atmosphere\nb electrical forces arc between two positive areas\nc high - pressure air masses move faster than low - pressure air masses\nd sound waves travel slower than light waves

Answer

Brief Explanations:

Light travels at a much faster speed (approx. 300,000 km/s in a vacuum) than sound (approx. 343 m/s in air at room - temperature). So when a thunderstorm occurs, the light from the lightning reaches our eyes almost instantaneously, while the sound of thunder takes longer to reach our ears.

Answer:

D. sound waves travel slower than light waves
