Very much so.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
No known particles can travel faster than the speed of light in a vacuum, according to the theory of special relativity. In a medium like water, particles such as neutrinos can travel faster than the speed of light in that medium, but not in a vacuum. In solids, sound waves can propagate faster than light as well.
The question has no sensible answer: the Mach number is the speed of an object in a medium compared to the speed of sound in the same medium. Light, and other electromagnetic radiation travel fastest in vacuum. Since sound cannot travel in vacuum its speed in vacuum is 0 and so the Mach number for light requires division by zero - which is undefined.The Mach number for light travelling in air is approx 873,300. In water, it is 202,000 and in diamond it is only 10,400.
By definition, Mach 1 is the speed of sound. Most of the time it is used to refer to the speed of sound in air, but it can be used to refer to the speed of sound in any fluid. Mach numbers are multiples of this speed, so Mach 0.5 is half the speed of sound while Mach 2.5 is two and half times the speed of sound. The term "transonic" refers to a condition where the speed crosses over the speed of sound - so it refers to a range of velocities of airflow exist surrounding and flowing past an air vehicle or an airfoil that are concurrently below, at, and above the speed of sound in the range of Mach 0.8 to 1.2. In this respect - at least some of the velocities must be below the speed of sound, some at the speed of sound and some faster. The correct term for speeds that are exclusively faster than Mach 1 is supersonic.
No, Mach 20 is not faster than the speed of light. The speed of light is approximately 299,792,458 meters per second in a vacuum, while Mach 20 is roughly 7.35 kilometers per second. Therefore, Mach 20 is significantly slower than the speed of light.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.

A speed that is more than five times faster than the speed of sound is equivalent to Mach 5. In this case, the speed range you provided, 3820-7640 mph, falls within the Mach 5 category.
Mach 5, 5 times faster than the speed of sound!
A supersonic plane is one that is flying faster than the speed of sound, or Mach 1. A hypersonic plane flies at a speed of Mach 5, so is much faster than a supersonic plane. Mach numbers are used for speeds greater than the speed of sound.
Bullets flies at the top speed of Mach 3 but almost Mach 4. There are some planes that can fly much faster than bullets but bullets used to fly faster than most planes(aircraft). Hypersonic aircraft can fly up to Mach 9. So yes, hypersonic aircraft can fly much faster than bullets. If these hypersonic planes can fly faster than bullets, they can fly alot faster than missiles. Missiles also flies around Mach 3 but hypersonic planes don't fly at that kind of speed. The top speed that hypersonic planes is nearly Mach 10(almost 10 times faster than the speed of sound).
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
* The speed of light in a vacuum, * The speed of sound,
Chuck Yeager is the first person to fly faster than sound (breaking the sound barrier), or MACH 1, on October 14, 1947 during level flight at an altitude of 45,000 ft.
It depends on whether you are referring to the tv show or the comics. In the tv show the flash's top speed is mach 6.6.In the comics he is 56,000,000,000,000,000 times faster than the speed of light.
