Detailed Solution

The speed of light is almost

1 0^{6}

times higher than the speed of sound.
Sound travels much less than the speed of light. The speed of sound in air is approx

340 m / \sec

. In comparison, light travels through the vacuum at a speed of

3 \times 1 0^{8} m / \sec

. The speed of light and sound varies in different mediums.
We know the speed of light is

300 \times 1 0^{6} m / \sec

. and the speed of sound in the air is

340 m / \sec

which is

1 0^{6}

times slower than the speed of light.
