Vocabulary #5

1.Mass: The amount of matter in an object.

2.Volume: The amount of space an object takes up.

3.Weight: (On earth) a measure of the force of gravity between earth and an object.

4.Density: A measure of how tightly packed matter is; the amount of mass contained in a given volume.

7.Insulate: Don"t allow heat or electricity to flow trough readily.

Vocabulary #4

1.Electromagnetism: The production of magnetism by electricity and the production of electricity by magnets.

2.Electromagnetic spectrum: All the wavelenghts of visible and invisible in order from short (gamma rays) to long (radio)

3.Laser: A device that produces a thin  stream of light of just a few wavelenghts.

Vocabulary #3

1.Prism: A piece of clear glass or plastic with two opposite sides in the shape of a triangle or other  geometric shape.

2.Spectrum: A band of colors produced when light goes through a prism.

3.Primary color: Red,green,or blue;mixing this colors can produce all the colors of the spectrum.

4.Primary pigment: Magenta.cyan,yellow;material with any of these colors absorbs one primary color of light and reflects the other two.

Vocabulary #2

1.Opaque:Completely blocking light from passing through.

2.Transparent:Leting all light through,so that objects on the other side can bee seen clearly

3.Translucent:Letting only some light through,so that object 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 that the edges) and bring light rays together.

7.Concave lens:A lens taht curves inward (is thicker at the edges than the middle) and spreads light rays apart.

Vocabulary #1

1.Bioluminescene:light produced by living organisms

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

3.Law of reflection:The angle of an incoming light ray equals the angle of the reflected ray.

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

5.Convex mirror:A mirror that curves out on yhe shiny side 

What is plasma?

In physics and chemistry,plasma is a substance similar to gas in wish  a certain portion of the particles are ionized.The presence of a non-negligible number of charge carries make the plasma electrically conductive so that it  responds strongly to electromagnetic fields.Plasma,therefore,has properties quite unlike those of solids,liquids or gases and is consedered to be a distinct state of matter.Like gas,plasma does not have a definite shape or a definite volume unless enclosed in a container;unlike gas,in the influence of a magnetic field,it may form structures such as filaments,beams and double layers.Some common plasmas are stars and neon signs.

Science Album #1

Description:This science album is about the different types of invisible light



1.Radio Wave:Radio Waves are a type of electromagnetic radiation with wavelenghts in the electromagnetic spectrum longer than infrared light.Like all other electromagnetic waves,they travel at the speed of light.Naturally-occurring radio waves are made by lighting,or by astronomical objects.

2.MicroWaves:MicroWaves are electromagnetic waves with wavelenghts ranging from as long as one meter to as short as one milimeter,or equivalently,with frequencies between 300 MHz (0.3 GHz ) and 300 GHz.

3.Infrared Light:Infrared ligt is electromagnetic radiation with a wavelenght between 0.7 and 300 micrometers wich equates to a frequency range between aproximately 1 and 430 THz.Wavelengts are longer than that of visible light but shorter than that of terahertz radiation microwaves.

4.Ultraviolet Light:Ultraviolet light is electromagnetic radiation with a wavelenght shorter than that of visible light,but longer than x-rays,in the range 10 nm to 400nm and energies from 3eV to 124eV.It is so named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the colour violet.

5.X- Rays:X radiation is a form of electromagnetic radiation.X-rays have a wavelenght in the range of  0.01 to 10 nanometers,corresponing to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 120eV to 120keV.They are shorter in wavelenght than UV rays and longer than Gamma Rays8

 6.Gamma Rays:Gamma radiation, also known as gamma rays,is electromagnetic radiaton of high frequency.They are produced bi sub-atomic particle interactions such as electron-positron annihilation,neutral pion decay,fusion,fission or inverse Compton scatering in astrophysical processes.
