Lesson 7: Visible Light and Ultraviolet Radiation PDF

 It ranges from 4x1014 Hz to 8x1014 Hz with wavelengths of 4x10-7 m to 8x10-7m are the only ones seen by our naked eye....

 It ranges from 4x1014 Hz to 8x1014 Hz with wavelengths of 4x10-7 m to 8x10-7m are the only ones seen by our naked eye. – the sequence of colors of visible light from longest to shortest. has the longest wavelength and has the shortest. In modern usage, is not usually distinguished as a separate color. https://images.app.goo.gl/88ov3LeA6rtGzhuG9 The visible light shares the slice in the electromagnetic spectrum. It lies in the infrared and the ultraviolet rays. It is the by the human eye. If not because of the visible light, we will not be able to see the beauty of our surrounding much less appreciate it. It helps us see objects. It is also used in traffic lights, commercial displays, car headlights, and tail lights. Television, liquid crystal display, and touchpad devices. It is also used by plants in.  using light emitting diodes is an emerging form of wireless communication technology. It can be used for simultaneous https://images.app.goo.gl/eUvf878nFAYa4GRH6 audio and video streaming. The that replaced telephone wires use visible light to transmit signals at high speed and/or long distance. https://images.app.goo.gl/JyYJKi98W2x15wtW9  or Light Amplification by Stimulated Emission of Radiation Laser light is used in many medical procedures: optical imaging, surgery, endoscopy, and treatment. Laser light is also used in biomedical research and microscopy.  is the emission of light when an object is heated to a high temperature. Examples are burning wood or charcoal and electric bulbs. is the emission of light by objects without a significant increase in their temperature. is a form of luminescence exhibited by living organisms possessing a light-producing substance called catalyzed by the enzyme. Fireflies and glow worms are familiar examples of bioluminescent organisms. It is a region with frequencies ranging from and wavelengths ranging from. Most popularly known as.  It was discovered by the German physicist. https://images.app.goo.gl/Ateph9V7tJSnRJHo6  – has a wavelength range of 315 nm to 400 nm. It accounts for 95% of the solar UV reaching the Earth. – wavelengths from 280 nm to 314 nm and is filtered by the ozone in the atmosphere. – wavelengths from 60nm to 279 nm and is almost completely absorbed by the atmosphere and does not reach the Earth’s surface. https://www.google.com/imgres?imgurl=https%3A%2F%2Fwww.mcomarin.com%2Fwp- content%2Fuploads%2F2021%2F12%2Fezgif.com-gif-maker-11.jpg&imgrefurl=https%3A%2F%2Fwww.mcomarin.com%2Fthe-abcs- of-ultraviolet-radiation%2F&tbnid=N42U9A_g67JGKM&vet=1&docid=o6rR51hQ-fDS7M&w=960&h=560&source=sh%2Fx%2Fim  is used to treat skin conditions like psoriasis and vitiligo that cause depigmentation of parts of the skin. stimulates the production of vitamin D in our body.  is the major source of ultraviolet rays. also emit UV rays. , more popularly known as , are used to detect forged bank notes. Black light makes visible the security marker ink that we use for our signatures in our bankbook. It is used during the at crime scenes, in procedures like searching for traces of blood and other body fluids, fingerprints, and footprints. Black light is also used to. It is also and fly traps, as well as in theaters to produce the “glow in the dark” effect.
