Distance vs Time Delay
Sound Distance
By measuring the time between seeing an event and hearing it, you can estimate the distance.
Formula
d = v_sound * t
where v_sound = 331.3 + 0.606 * T (m/s). A classic application: counting seconds between a lightning flash and thunder to estimate storm distance.
Example Calculation
Thunder arrives 3 seconds after lightning at 20 degrees C.
- 01v = 331.3 + 0.606 * 20 = 343.4 m/s
- 02d = 343.4 * 3
- 03d = 1030.3 m
- 04d = 1.030 km (about 1 km)
