What is a supersonic airplane?

An example of the upersonic technology used in warplanes is the F-16 warplanes. What is sound? What is the speed of sound? Sound is the name given to the periodic pressure changes that living things perceive with their hearing organs. If you ask what is its physical dimension, we can say that it is a simple mechanical disorder that occurs in sound, solid liquid or gas environments… Molecules in a substance vibrate to create sound. Sound produced by vibration is actually a form of energy. Sound is measured in decibels and is briefly represented as db. The sound power of a normal person is between 50 and 60 decibels. Any sound above this disturbs us. For example, loud noise produces 90 decibels, and while the missile is taking off, it produces 120 decibels. The speed of propagation after sound is produced is called the speed of sound. Based on normal sea level and a temperature of 20 degrees Celsius, the speed of sound is 343.2 meters in 1 second. It does not change according to th

What is Kirlian Photography? Aura Photography Revealed

If you're a curious photographer who likes to explore lesser-known areas of photography, you've probably heard of Kirlian photography . The Kirlian photography technique is a truly extraordinary way of capturing a variety of subjects. Many believe it indicates the aura of people or moving objects. This is why Kirlian photography is a mystery, especially for amateur photographers. Introduction To Kirlian Photography Kirlian photography was officially invented in 1939 by Semyon Davidovitch Kirlian, although it can be traced back to the late 1700s. The Kirlian photography process reveals visible "auras" around the objects being photographedThese photos have been the subject of many legends and controversies over the years. Interestingly, many were originally used to explain the Kirlian phenomenon, put forward by the inventor himself and his wife. Kirlian photography is relatively simple and doesn't even require the use of a camera. First, a l

Optical Systems

Fiber optic, which started to be used in the 1920s, did not attract much attention due to the expensiveness of the material and the lack of usage area, and in the last 20 years, the potential in its technology was realized and it has found a very intensive use area. Fiber optic technology, which started to be used primarily in the field of medicine, is used in almost every field today. Two techniques such as "fiber optic cables" and "optical systems" are used to transmit light today. With optical fiber, a large amount of information is transmitted at the speed of light along a single fiber cable. A large number of phone calls, television broadcasts and internet connections can be made at the same time from the finger-thick fibers in the fiber optic cable. In fiber optic systems, electromagnetic waves at different frequencies can be transmitted over long distances without any change. The working principle of fiber cable is based on full reflection of light. Light
