Electromagnetic Waves Properties
Electromagnetic Waves Properties: This article has been told about Electromagnetic Waves Properties. Hope the students will get help from this article.
So let us know what are Electromagnetic Waves Properties?
- No medium is require for the propagation of electromagnetic waves.
- These waves can also propagate in a vacuum.
- These waves are transverse waves arising from the oscillations of magnetic and electric fields, e.g. light waves, thermal radiation, X rays, radio waves, etc.
- The wavelength of these waves is very wide.
- Their range is 10-14 m. to 104 m. Happens till.
Waves are mainly divided into two parts:
- Machanical Waves
- Non- Machanical Waves
(i) Mechanical Waves: Waves that propagate in a material medium (solid, liquid, or gas) calls mechanical waves.
(ii) Mechanical wave or electromagnetic wave: Waves that do not require any medium for propagation, that is, waves can also propagate in a vacuum, which calls electromagnetic or non-mechanical waves.
Electromagnetic Waves Properties
- There is no charge on these waves, that is, they are neutral waves.
- These waves have both momentum and energy.
- The speed of electromagnetic waves is equal to the speed of light
- Electromagnetic waves exert pressure on the surface they strike
- Electromagnetic waves propagate or travel with the speed of light.
- In these waves, the electric field, the magnetic field and the transmission vector, all lie perpendicular to each other.
- The concept of these waves was first presented by Maxwell, so we can say that electromagnetic waves were discovered by Maxwell.
- These are transverse waves, that is, the oscillations of these waves are perpendicular to the direction of propagation.
Major Electromagnetic Waves :-
Gamma-rays Inventor: Bekural Wavelength Range: 10^-14m to 10^-10m Frequency Range Hz: 10^20 to 10^18 Uses: It has high penetrating power, it is used in the nuclear reaction and artificial radioactivity. X-rays Inventor: Ronjan Wavelength; Range: 10^-8m to 10^-7m Frequency Range Hz: 10^18 to 10^16 Uses: It is used in the medical and industrial field. ultraviolet rays Inventor: Ritter Wavelength; Range: 10^-8m to 10^-7m Frequency Range Hz: 10^16 to 10^14 Uses: Used to aerate, produce photoelectric effect, destroy bacteria. Visible Radiation Inventor: Newton Wavelength Range: 3.9 x 10^-7m to 7.8 x10^-7m Frequency Range Hz:10^14 to 10^12 Usage: It allows us to see objects.
Important Points For Electromagnetic Waves:
- Its existence is due to the oscillation of electric field and magnetic field.
- Its speed in other mediums is less than its speed in zero.
- It is a transverse wave.
- In this, the electric field and the magnetic field oscillate perpendicularly to each other.
- The speed of light in zero or vacuum is about 3 lakh km/s which is a constant. No object can accelerate faster than this.
- The part of the electromagnetic radiation that the human eye is sensitive to is called visible light.
- The wavelength of visible light ranges from 4000 angstroms to 8000 angstroms.
- Both electricity and magnetism are electromagnetic effects.
- Electromagnetic radiation also has energy and momentum. When these waves react with a substance, they provide energy and momentum to the molecules (atoms or electrons) of the substance.
