Question

the speed of light is about 300,000,000 meters per second. that’s about 3×10^8 meters per second. the speed of sound in dry air is about 3×10^2 meters per second. which travels faster?

Explanation:

Step1: Compare exponents

The exponent of \(10\) for light speed is \(8\) and for sound speed is \(2\). Since \(8>2\), \(3\times 10^{8}>3\times 10^{2}\).

Answer:

Light travels faster.
