Step-by-Step Solution:

Solution 11E Step 1: 8 The speed of light and sound are different. Speed of light, c = 3 × 10 m/s Speed of sound in air, v = 340 m/s The sound of the gun and the smoke are originating at the same time. Since it is travelling at different speeds, there will be a specific time lag between the light and the sound.
