How does laser invention work
WebAug 4, 2024 · Bear with us, the answer is technical. Lasers release energy by emitting laser beams of specific wavelengths. When the beam hits the surface, the material reflects most of its energy. The remaining energy is absorbed and converted into heat. For laser etching, the material must absorb just enough energy to melt. WebWith adaptive cruise control, your car uses radar and laser sensors to detect the speed of vehicles ahead and then adjusts your own speed accordingly to keep a safe distance. So, if the car in front of you slows down, your car will too. Once they’re out of the way, your adaptive cruise control will accelerate back to the speed you previously set.
