VOCABULARIO 4

ELECTROMAGNETISM: the production of magnetism by electricity and the production or electricity by magnets.

ELECTROMAGNETIC SPECTRUM: all the wavetengths of visible and invisible light in order from short (gamma rays( to long (radio)

LASER: a device that produces a thin stream of light of just a few close wavelengths.

VOCABULARY 5

Matter: is everything that has mass, volume and density.

Mass: the amount of matter in an object.

Volume: the amount of space an object takes up.

Weight: (on Earth) a measure of the force of gravity between Earth and  an object.

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

Buoyancy: the upward push on an object by the liquid (or gas) the object is placed in.

Conduct: allow heat or electricity to flow through readily.

Insulate: not allow heat or electricity to flow through readily.

INVESTIGATION (PLASMA)

Plasma: In physics and chemistry, is called to a gas plasma consisting of free charged particles.

ALBUM 1 (INVISIBLE LIGHT)

RADIO WAVES

Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Like all other electromagnetic waves, they travel at the speed of light.

MICROWAVES

Microwaves are electromagnetic waves with wavelengths ranging from as long as one meter to as short as one millimeter, or equivalently, with frequencies between 300 MHz and 300 GHz.

INFRARED LIGHT

Infrared light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometres.

ULTRAVIOLET

Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than x-rays, in the range 10 nm to 400 nm.

X RAYS

X rays is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz.

GAMMA RAYS

Gamma radiation, also known as gamma rays, is electromagnetic radiation of high frequency (very short wavelength). They are produced by sub-atomic particle interactions such as electron-positron.

VOCABULARIO 3

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

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

Primary Color: red, green, or blue; mixing these colors can produced all the colors of the spectrum.

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