Visible Light ● Explain how, when, and by whom this type of radiation or wave was discovered.
Visible light was discovered in the early 19th century by William
Herschel and Johann
Wilhelm Ritter, Thomas Young, Thomas Johann Seebeck, and others. The concept became more and more clear as light outside the visible range was discovered.
● Give a physical description of the wave, including frequency, wavelength, energy and wave speed.
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. When white light shines through a prism, the white light is broken apart into the colors of the visible light spectrum. Water vapor in the atmosphere can also break apart wavelengths creating a rainbow. ● Compare the wavelength of your wave to an everyday object. How does the the size compare? Infrared lights have wave lengths about similar to the size of bacteria having a range from about 10^­6 to 10^­5 meters. The source of infrared usually comes from 100W light bulbs. ● Provide examples of practical (everyday) uses of/exposure to this particular wave.
Light waves are given off by anything that's hot enough to glow
. its the light given off by the sun and reflected by all objects we can see. Light waves can also be made using a laser.
● Illustrate the source of the wave (how is it “created”?)­where does it occur naturally? Where is it synthetic?
It occurs naturally from the sun, thats where most of the light comes from. and is not synthetic unless coming from a heat source such as a laser or flashlight.
● Information on benefits of this type of electromagnetic radiation. The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by destroying the disease producing pathogens and microorganisms like bacteria, virus & fungi.
● Examples of occupations which utilize this type of radiation.
Examples would include Food and drink irradiators, salon workers and patrons, laboratory workers lighting technicians lithographic
