Aloud explosion will produce a amplitude sound wave.

HIGH

Explanation:

The amplitude of a sound wave signifies its loudness or volume. Larger amplitude sound waves describe a louder sound and, on the other hand, a smaller amplitude depicts a softer sound. These sound waves carry energy from one medium to another medium by its mode of vibration. In case of vibration with high energy, the molecules present in it moves strongly and rapidly, depicting a larger amplitude wave.

Thus, a loud explosion will produce a high amplitude sound wave.

by 1880, germany had more rail lines than great britain and russia.
