Answer is Right!
Answer is Wrong!
The correct answer is D. 21453.
Light travels faster than sound. This is because light is a wave of electromagnetic radiation, while sound is a wave of pressure. Electromagnetic waves travel at the speed of light, which is about 300,000 kilometers per second. Sound waves travel at a much slower speed, which depends on the medium through which they are traveling. In air, sound travels at about 343 meters per second.
This means that if you see lightning, you will hear the thunder about 3 seconds later. This is because the light from the lightning travels to you much faster than the sound of the thunder.
The other options are incorrect because they do not reflect the fact that light travels faster than sound.
