SUMMARY
The delay between seeing lightning and hearing thunder is primarily determined by the speed of sound, which is calculated to be 340 m/s at 15°C. For a lightning strike 1.00 km away, the time delay is approximately 2.94 seconds. The time taken for light to travel the same distance is negligible at 3.3 x 10^-5 seconds, making it insignificant compared to the sound delay. Therefore, the total delay is effectively 2.94 seconds, as the light delay does not impact the overall perception of the event.
