https://mocomi.com/ presents:Discovery of Laser What is a laser? The full form of 'laser' is actually 'Light Amplification by Stimulated Emission of Radiation'. Did you know that we use lasers every single day? We use laser printers in offices, lasers to scan the bar codes on products when we buy them and doctors use lasers in life saving surgeries! But have you ever stopped to wonder exactly what a laser is and how it works? The light that we see around us is a mixture of beams at different wavelengths. Together they can be seen as 'White Light', which is colourless. Lasers, unlike natural light, do not occur in nature and are a creation of man. Scientists figured out how to artificially create this special kind of light. How can laser light cut through solid objects? A laser cannot be simply defined as a very strong torch. Lasers produce a narrow, intense beam of light, which is strengthened using a curved mirror. Unlike the light we see around us, the light from a laser consists of rays which are all at the same wavelength. Owing to this property, the waves of light in a laser travel in phase (with their peaks lined up). It is able to cut through things because of this intensity and the fact that it can be focussed into a very tiny spot. It is different from a simple beam of light in many ways. A laser is 'monochromatic'- only of one colour. This is because all the light in a laser beam is of the same wavelength. The rays of light in a laser are also ‘collimated’ - they can travel in beams parallel to each other, which allows them to travel in a straight beam for long distances. Lastly, the light is ‘coherent’, meaning that it moves in phase together. #DiscoveryofLaser #Laser #CasaAndAsa To learn more about Discovery of Laser? visit the best e-learning website here: https://mocomi.com/discovery-of-laser/ Watch more discovery videos here: https://www.youtube.com/watch?v=7TneZ1qSt2g https://www.youtube.com/watch?v=XTlHXd5Kx78 https://www.youtube.com/watch?v=f4BCIlaTE-g https://www.youtube.com/watch?v=9OJ7piwbbHc https://www.youtube.com/watch?v=CqlFvFNe1Nk https://www.youtube.com/watch?v=-XHx8Qgh0PI https://www.youtube.com/watch?v=v0NgOLF8f2M https://www.youtube.com/watch?v=VtQYjrs-8NY https://www.youtube.com/watch?v=16ceUARzMFs https://www.youtube.com/watch?v=MoCySRpGaL8 or watch interesting discoveries & inventions for kids here https://www.youtube.com/watch?v=CagjU0XPG_A&list=PL6vCwGtCTVtNvm8sshOWrGt9l_hUFyZOr Watch more educational content for Kids here: https://mocomi.com/ - Top educational website for kids, Subscribe here for new and interesting content every week ► ► https://www.youtube.com/mocomikids?sub_confirmation=1 Press Bell Icon 🔔 For Latest Updates.
