To control the effects of electromagnetic waves. Present a scientific basis on how to control EMW radiations through demonstration of project
What is an Electromagnetic Wave (EMW)? DEFINITION Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as ‘electromagnetic’ waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other. They are also perpendicular to the direction of the EM wave.They are deflected neither by the electric field, nor by the magnetic field.
Description
Used for the transmission of Electromagnetic Waves The transmission of electrical energy by wires, the broadcasting of radio signals, and the phenomenon of visible light are all examples of the propagation of electromagnetic energy. Electromagnetic energy travels in the form of a wave. Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency.

The Electromagnetic Spectrum
Your radio captures radio waves emitted by radio stations, bringing your favorite tunes. Radio waves are also emitted by stars and gases in space.
RADIO
Microwave radiation will cook your popcorn in just a few minutes, but is also used by astronomers to learn about the structure of nearby galaxies
MICROWAVE
Night vision goggles pick up the infrared light emitted by our skin and objects with heat. In space, infrared light helps us map the dust between stars.
INFRARED
Visible Our eyes detect visible light. Fireflies, light bulbs, and stars all emit visible

Ultraviolet radiation is emitted by the Sun and are the reason skin tans and burns. "Hot" objects in space emit UV radiation as well.
ULTRAVIOLET
A dentist uses X-rays to image your teeth, and airport security uses them to see through your bag. Hot gases in the Universe also emit X-rays.
X-RAY
Doctors use gamma-ray imaging to see inside your body. The biggest gamma-ray generator of all is the Universe.

The Electromagnetic Spectrum DEFINITION DESCRIPTION The Electromagnetic The electromagnetic Spectrum. The spectrum is a continuum electromagnetic (EM) of all electromagnetic spectrum is the range of waves arranged according all types of EM radiation. to frequency and Radiation is energy that wavelength. The sun, travels and spreads out as earth, and other bodies - the visible light it goes radiate electromagnetic that comes from a lamp in energy of varying your house and the radio wavelengths. The waves that come from a spectrum of waves is radio station are two divided into sections types of electromagnetic based on wavelength radiation.

Conclusion If the source of the sounds is from the phone the partial blocker is an aluminum foil because it can shield to block loud noises and sound vibrations, as for the non blockers are cotton clothing, paper, rubber gloves because the sound vibration can pass through these. As for the remote control the partial blockers are cotton clothing this can block the magnetic wave from the remote control, as for the non blockers are plastic wrapper, paper, rubber gloves because the magnetic waves can pass through these things easily.
