The structure and working principle of mechanical clocks
Aug , 17 2020
There are many structural forms of mechanical clocks, but their working principles are basically the same. Clocks and watches are mainly composed of the prime mover system, transmission system, escapement governor, pointer system and winding needle system. The mechanical clock uses a clockwork as the motive force of the driving system, and drives the escapement governor to work through a transmiss...

What is Electromagnetic Waves&How do electromagnetic waves travel?
Jan , 15 2021
Many people have questions about the relationship between electromagnetic wave frequency (wavelength) and signal coverage. Some people say that the higher the frequency of electromagnetic waves, the weaker the penetration, so the coverage is poor. So some people ask, X-rays and γ-rays are high in frequency, aren't they used for medical photography and metal equipment flaw detection? Some people ha...
