The speed of sound and the speed of light are not the same. In fact, the speed of light is significantly faster than the speed of sound. The speed of light in a vacuum is approximately 299,792 kilometers per second (186,282 miles per second), while the speed of sound in air is about 343 meters per second (767 miles per hour).
Because light travels much faster than sound, we can see things before we hear them in many situations. For example, if you observe a distant event, such as a lightning strike, you will typically see the flash of light before you hear the accompanying thunder. This is because light travels almost instantaneously over large distances, while sound takes time to propagate through the air.
To give you an idea of the time difference, light travels at a speed of about 300,000 kilometers per second, whereas sound travels at a speed of about 343 meters per second. Therefore, for every second it takes for sound to travel approximately 1 kilometer, light can travel about 300,000 kilometers. This significant difference in speed allows us to see distant events before we hear them.
It's important to note that the speed of sound varies depending on the medium through which it travels. For example, sound travels faster through water than through air. However, even in the most favorable conditions, the speed of sound is still much slower than the speed of light.
