1, therefore, infrared can only penetrate the gap between atoms and molecules, but can not penetrate the interior of atoms and molecules, because infrared can only penetrate the gap between atoms and molecules, it will speed up the vibration of atoms and molecules, and expand the distance, that is, increase the energy of thermal motion, from a macro point of view, the material is melting, boiling, and vaporizing. But the essence of matter (atoms, molecules themselves) does not change, which is the thermal effect of infrared.
2, infrared is part of the electromagnetic spectrum, wavelength mediumInvisible between microwaves and visible light, it has a thermal effect and can be used in medical, civil and military fields. Rays usually refer to X-rays and gamma rays, which are short wavelength radiation in the electromagnetic spectrum, with high energy and strong penetration, and are often used in medical imaging and industrial testing.
3, laser is laser, but the former is transliteration. Plasma is plasma. It's called a different thing. The directed energy weapon shouldn't bleed when it hits the soft tissue, given the charred wound.
4, radiation electromagnetic wave has a certain harm to the human body, can promote cell cancer, can make hormones abnormal, make calcium ionsRapid loss, can lead to dementia, may lead to pregnancy abnormalities. Laser is actually a laser, laser is a relatively early name, now called laser. Laser has good orientation and high brightness, and is widely used in ranging, radar, optical fiber communication, medicine, missile guidance and nuclear fusion experiment.
1, it can be connected with mobile devices or computers through wireless, Bluetooth, data cable, support laser virtual laser projection, can be projected on any flat surfaceUse it as a keyboard. We determine the position that can be clicked through the optical principle, and then complete the information we need to input, they are keyboards without actual objects, the volume is particularly small, it is particularly convenient to carry, and can adapt to the environment of special work.
2, the Bluetooth keyboard can be charged with a charging bank, all are usb ports, and the voltage and current are basically the same, so you can charge the Bluetooth keyboard.
3. No. Three-mode keyboard can not be charged with a charging bank, three-mode keyboard is wired, Bluetooth, 4G three connection modes are supported, usually on behalf of the keyLaser '> Who can explain laser
1, the original Chinese name of LASER is called "laser", "Leser", is the transliteration of its English name laser, is taken from the English Light Amplification by Stimulated Emission of Radiation of the first letter of the word composed of the abbreviation. It means "light amplification by stimulated radiation". The full English name of laser has fully expressed the main process of manufacturing laser.
2, laser technology core laser radiumThe core of spotlights is laser technology. Laser is a phenomenon of light amplification produced by stimulated emission. In the laser laser lamp, the laser device makes the atom or molecule in the working substance transition from a high energy level to a low energy level through a specific excitation method, such as electrical excitation or optical excitation, and produces light radiation. These light radiation are collimated and focused by the optical system to form a bright, stable beam.
3, LASER, once translated as "laser" or "Leser", its English name laser is Light Amplification by Stimulated Emission ofRadiation: amplification of light by stimulated radiation This concept was discovered by the famous physicist Albert Einstein in 1916, and it was not until 1958 that the laser was successfully manufactured.
4, laser is a form of application of laser. Laser is a way of using laser technology for applications. Laser is a kind of high energy beam, which has the characteristics of single stable wavelength and strong directivity. Laser technology achieves accurate processing or detection of objects by directing laser to the target object. Specific applications of laser Laser technology is widely used in industrial fields.
