The speed of everything – light ,sound and much more

Speed of Radio Waves
Radio waves are generally produced by moving charged particles. They have frequencies as low as 30 hertz or as high as 300 gigahertz.

Radio waves are generated by transmitters and received by receivers using antennas. In a vacuum, radio waves can travel at the speed of light, i.e., 299,792,458 meters per second.

Radio waves. Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz to as low as 30 hertz. At 300 GHz, the corresponding wavelength is 1 mm, and at 30 Hz is 10,000 km.

 

Speed of a Bullet Train
The first bullet train line was launched in Japan and the line connected Tokyo to Osaka, one of about 340 miles. The trip was of about two and a half hours and had a maximum speed of 150 –200 mph.

Bullet Train. Shinkansen uses a 25 kV AC overhead power supply (20 kV AC on Mini-shinkansen lines), to overcome the limitations of the 1,500 V direct current used on the existing electrified narrow-gauge system. Power is distributed along the axles of the train to reduce the heavy axle loads under single power cars. The ALFA-X version of the Shinkansen train began three years’ worth of test runs on Friday. Once it enters operation sometime around 2030, it will run at speeds of up to 360 kph (224 mph), comfortably making it the world’s fastest bullet train.May 10, 2019

 

Speed of a F1 Racecar
F1 Race Cars have been one of the fastest race cars for years now and they can accelerate from 0 to 62 mph in less than 2 seconds. Although the F1 cars are fast, their development and improvements are done slowly and steadily.

A modern F1 race car can rev up to 18,000 RPM and 750 HP or more.

The F1 race car can travel up to 212 mph

F1 Race Car. Founded1950. Cars are completely identical and drivers are backed by the same race engineers to ensure that talent shines over the cars specs. … Both the Williams F1 car of Formula 2 racing and the variety of F1 cars are fitted with a V8 engine, but Formula 2 vehicles sport an rpm of 10,000 while F1 cars hit up to 18,000 rpm.Apr 26, 2018

Speed of a Racehorse.  

Horse racing has been an entertaining event for many centuries now. It was and still is a competitive event for humans. People place bets and some even fix races to earn some money with horse racing.

The average speed at which a horse gallops is around 48.2 kilometers per hour(43.97 miles per hour). However, the fastest racehorse in the Guinness Book of Records has a top speed of 70.76 kilometers per hour(43.97 miles per hour).

Sport of kings. Breeds that are used for flat racing include the Thoroughbred, Quarter Horse, Arabian, Paint, and Appaloosa. Jump racing breeds include the Thoroughbred and AQPS..

 

Speed of a Cheetah
Cheetah is one of the fastest land animals on Earth. You might be curious to know how fast it can run. A human cannot beat a cheetah unless they go head to head in a long run.

Cheetahs sneak up on their prey and sprint to attack them. They do so at speeds as high as 75 mph or 120 km/hr. The top speed may also range between 65 and 75 mph but has an average speed of only 40 mph. It also accelerates from 0 to 60 in 3 seconds or reaches up to 47 mph in two seconds.

However, it runs at such high speeds only in short bursts.

Cheetah. The cheetah is a large cat of the subfamily Felinae that occurs in North, Southern and East Africa, and a few localities in Iran. It inhabits a variety of mostly arid habitats like dry forests, scrub forests, and savannahs.  Cheetahs do not roar like lions or tigers.

Speed of a Human
It only seems fair to include the speed of a human when we talk about the speed of everything else.

Usain Bolt is considered one of the fastest humans on the planet and he has clocked about 27mph in his 100 sprints. Although it is not fast enough to beat a cheetah, it is enough to outrun other animals.

In theory, humans should be able to run as fast as 35-40 mph, based on the strength of muscles, capacity, and various other factors.
