As a subject matter expert in ballistics and physics, I can provide a detailed answer to your question regarding the speed of bullets compared to the speed of sound.
The speed at which a bullet travels is known as its muzzle velocity, which is the speed of the projectile as it leaves the barrel of the firearm. The speed of sound varies depending on the medium through which it travels and the temperature of the environment. At sea level and at 20 degrees Celsius, the speed of sound is approximately 343 meters per second (m/s). However, this can increase with higher temperatures and decrease with lower temperatures.
Bullets fired from firearms can travel at a range of speeds. Low-power handguns typically have muzzle velocities that are less than the speed of sound, meaning they are subsonic. These bullets travel at speeds below 343 m/s and therefore do not exceed the speed of sound in the surrounding air. As a result, the sound of the bullet traveling through the air is not heard until after the bullet has passed by.
On the other hand, high-power handguns and rifles can fire bullets at supersonic speeds, which means they travel faster than the speed of sound. For instance, a .44 Magnum, as mentioned in your reference, can have a muzzle velocity that exceeds 343 m/s. When a bullet travels at supersonic speeds, it creates a sonic boom, which is a loud noise that occurs when an object travels through the air faster than the speed of sound. This sonic boom is often heard as a crack or a thunder-like sound and can be heard before the actual gunshot, especially if the bullet is fired from a distance.
The sonic boom is created by the shock wave that forms when an object moves through the air at supersonic speeds. As the bullet moves forward, it compresses the air in front of it, creating a shock wave. This shock wave then moves through the air at the speed of sound, and when it reaches the observer, it is heard as a loud noise. The shock wave can also cause damage to structures and can be felt as a physical impact, especially if the bullet is traveling very close to the observer.
It's important to note that the speed of a bullet does not remain constant throughout its flight. Due to factors such as air resistance and gravity, the bullet will gradually slow down as it travels through the air. This deceleration means that a bullet that was initially supersonic may become subsonic at some point during its flight, depending on the distance it travels and the initial muzzle velocity.
Additionally, the speed of sound itself can be affected by altitude, as the air is less dense at higher elevations, which can cause the speed of sound to decrease. This means that a bullet might travel faster than the speed of sound at lower altitudes but slower at higher altitudes.
In conclusion, whether a bullet travels faster than the speed of sound depends on the type of firearm and the muzzle velocity of the bullet. Low-power handguns generally fire subsonic bullets, while high-power handguns and rifles can fire supersonic bullets. The sonic boom created by supersonic bullets is a distinct phenomenon that can be heard and felt by observers, and it is an important aspect to consider in the study of ballistics and the physics of sound.
