content: Light travels at an extremely fast speed of about 299,792 kilometers per second in a vacuum, while sound travels much slower at around 343 meters per second in dry air at room temperature. Light can travel through a vacuum, whereas sound requires a medium to propagate, like air or water. These differences in velocity play a significant role in how we perceive and use light and sound in various applications.
response: Since light travels faster than sound, people may appear bright until you hear them speak. (Image:A light bulb next to a person speaking with speech bubbles containing words like 'uh-oh' or 'oops')
