Question

Write six properties of em spectrum. ​

Answer 1

Answer:

these are the properties of em waves.

Explanation:

1. Electromagnetic waves are transverse in nature as they propagate by varying the electric and magnetic fields such that the two fields are perpendicular to each other.

2. Accelerated charges are responsible to produce electromagnetic waves.

3. Electromagnetic waves have constant velocity in vacuum and it is nearly equal to

3×108ms−1 which is denoted by C = 1√μoϵo.

4. Electromagnetic wave propagation does not require any material medium to travel.

5. The inherent characteristic of an electromagnetic wave is its frequency. Their frequencies remain unchanged but its wavelength changes when the wave travels from one medium to another.

6. The refractive index of a material is given by:

n = √μrϵr.

hope u understand easily.

Answer 2

Answer:

• The whole distribution of electromagnetic radiation which by virtue of their wavelength or frequency is called as Electromagnetic spectrum.
• It include all the radio waves .
• It contain the entire spectrum from lowest to highest frequency.
• It is typically described by following of three properties :

1. Intensity (I)
2. Frequency (f)
3. Wavelength (λ )

• Sunligth is also consider under electromagnetic spectrum.
• Following are the properties of EM spectrum.

1. Electro magnetic Theory : by this magnetism and electricity treat to be separate forces.
2. Waves and field :When electron (atomic particle ) is accelerated by electric field,cause to move it ,is created by EM radiation.
3. Radio waves.
4. Microwaves
5. Infrared
6. Visible light
7. Ultraviolet
8. X-rays
9. Gamma-rays
