The Characteristics of Electromagnetic Wave

The Characteristics of Electromagnetic Wave

1. Changes in the electric field and magnetic field occurs at the same time, so that the two fields have a maximum and minimum prices at the same time and at the same place.

2. The direction of electric field and magnetic field perpendicular to each other and both perpendicular to the direction of wave propagation.

3. From feature number two is obtained that electromagnetic waves are transverse waves.

4. Like the waves in general, electromagnetic wave reflection events experienced, refraction, interference, and diffraction. Also experienced a polarization of the incident because it includes a transverse wave.

5. Propagation of electromagnetic waves depends only on the properties of electric and magnetic medium taken

The Function of Electromagnetic

Wave

• Gamma rays.

frequency : 1020 hz - 1025 hz Length of wave : 10-13 – 10-10

used to spay destructive insects like fruit flies plants.

widely used for the testing of welding-weld. Types of radiation sources used will affect the penetrating power in the direction of material thickness

Kamera Gamma

• X Rays. (=sinar rontgen)

> frequency : 1016 hz - 1020 hz It can pass through the paper,

cloth , and flash but., it can’t pass through the

metal and bones.

> used to detect the organ in the body organs.

 

• Ultra Violet.

> The main source is the sun required in the process of

assimilation of plants killing some kind of skin disease

germs

• Visible Light

> The only one of Electromagnetic wave that can be viewed

The length of wave: 430 nm -sd- 690 nm)

• Infrared frequency: 10^11 hz -sd- 10^14 hz The length of wave : 10-6m - 10-5 m

> used in photography (shoting from the air or satellite) for mapping the surface of the earth and natural resources

• Radio Detection and Ranging to detect that the plane moved closer / away from the air base. dapat juga dipakai pada sarana komunikasi.

 • Microwaves Used for communication Used for cooking equipment (microwave oven)

• Radio Waves Frequency : 104 Hz – 108Hz The length of wave : 10 m – 104m Used for communication The radio waves can be divided into two :

1.AM (Amplitude modulation) that can reach very far distance

2. FM (Frequency modulation) that can’t reach far distance
