Vocabulary # 4

1.electromagnestism: the production of magnetism by electricity and the production of electricity by magnets.

2.electromagnetic spectrum: all wavelenght of visible and invisible light in order from short (gamma rays) to long (radio).

3.laser:a device that produces a thin stream of light of just a few close wavelenghts.

Vocabulary #3

prism: a cut piece of clear glass (or glass) with two opposites side in the shape of a triangle or other thegeometric shape.

spectrum: a band of colors produced when light goes through a prism.

primary colors: red,gree, or blue;mixing these colors can produce all the colors of the spectrum

primary pigment: magenta, cyan, yellow;material with any of these colors absorb one primary color of light ands rweflects the other two.

Vocabulary #2

1.opaque: Complety blocking light from passing through.

2.transparent: Letting all light through, so that objects on the other side can be seen clearly.

3.translucent: Letting only some light through, so that objects on  the other side appear blurry.

4.polarization: Allowing light vibrations to pass through in only one direction.

5.refraction: The bending of light rays as they pass from one substance into another.

6.convex lens: a lens that curves outward (is thicker at the middle than at edges)

7.concave lens: a lens that curves inward (is thicker at the edges than at the middle)

Vocabulary #1

1.Bioluminescence: light prosuced by a living organism.

2.Light ray: a straight-line beam of light as it travels outward from its source.

3.Law of Reflection: the angle of an incoming light ray equals the of the refected ray.

4.Concave mirror: a mirror that curves in on the shiny side.

5.Convex mirror: a mirror that curves out on the shiny side.

X Rays:0.1 billion of a meter, is a form of electromagnetic radiation, x-rays have wavelenght  They are shorter in wavelenghs than UV rays are longer than gamma rays the ditection of x rays is based on various methods are photographic plates, photographic film in cassetes, and rare earth screens.Some detectors are ginger counter etc. In 1895 Thomas Edison investigated materials ability to flouresce when expose to x-rays.

Gamma rays:Is a electromagnetic radiation of high frequency (very short wavelenght) they are produced by sub-atomic particle intractions such as electron-position amilition and other. When a gamma ray passes through matter, the probality for absortion in a thin layer is proportioinal ina thin layer to the thickness of that layer.

Blu-ray:Blue- ray disc was uses a "blue" laser oparating of wavelenght of 405 nm, to read and write data. The blue violet laser´s  shorter wavelenght makes it possible to store more information on 12 cm for audio, BD  ROM player are required to support Dobly digital. 

Conclusion: In my conclusion I think that investigated this topic ´was interesting so I learn for example about how to take care for the ultraviolet light also about the infrared and this are inside of the electromagnetic spectrum

Infrared light:700-400 billions of a meter, is a electomagnetic radiation with a wavelenght. IR are longer than radiation microwaves. IR  is used extensively for military and civilin purposes. Humans at normal body temperature radiate chiefly at wavelenght as, shown by Wien' s displacement law. The name means below red "below". Red is the color of the wavelenghts visible light.

Ultraviolet light:Is a electromagnetic radiation with a wavelenght shorter than  that of a visible light but longer than x rays. UV light is found in sunlight and is imitted electric areas and specialized light such as black light. Beneficial effects:

Vitamin D UV exprosure includes the production of the vitamin D in the skin other beneficial effects are aeslheticts, medical applications, harmful effects, medical organization recomended that patients protect themselves from UV radiation using sunscreen. Also can damage the eyes. IV light is used for quantification of nucleic acids.

Album: Invisible light

In this album you will see about the invisible light some of the invisible ligth is very imporatant in your live also  we can learn about differents types, so the invisible light travels in waves are two types: long and short.Examples:

Radio waves: 1,000 meters, is the longestwaves of the electromatic reaction. Carry signals in codes ( AM/FM )  like all the other electromagnetic waves, they travel at the speed of  light, artificially-generated radio waves are used for fixed and mobile radio comunication, broadcasting, and radar and other navegation system satellite comunication and computer network and inmurable other application.

Microwaves: 1 centimeter, is electromagnetic waves with wavelenght ranging from as a long, as one meter to 1 milimeter, or equivalintly , with frequeny between. As a conscuence, practical micowaves techine tends to move away from the describe resitor capacitors and inductors used with lower frequebcy radio wave.Vaccum tube devices operate on the ballistic motion of electrons.
