Transcript of VISIBLE LIGHT
2. medical practicioner
what imapact does the
ray have on you? where can you find these rays? anywhere you can see Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. visible light is used for the treatment of a variety of skin diseases and esthetic conditions in the form of lasers, intense pulsed light and photodynamic therapy. Visible light is also made use in many other machines today such as photoelectric copying machines, laser printers, CD players, FAX machines, optical recording media, and optical disc mass-storage systems of exceedingly high bit density. Seeing, Photography High-dose long wave visible light induces perinuclear vacuolization in vivo but does not result in early photoageing and apoptosis.
Burning, blindness ( if concentrated ) Too much light can damage the retina in the eye. Visible light can induce indirect DNA damage through the generation of reactive oxygen species ( ROS are chemically-reactive molecules containing oxygen. Examples include oxygen ions and peroxides. ). As a medical practitioner if one is exposed to more than the acceptable amount of dosages, ocular damage, especially later in life, and may be related to the development of age-related macular degeneration. Itching and redness of eyes Done By: Kee Bei Bei, Tricia Chua, Liaw Shao Yi, B.Priyadharshini,Lin Yurun 2H The visible spectrum(the portion of the electromagnetic spectrum that is visible to the human eye. ) is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. It would allow me to have an increase in the range of things i can sell.
