TRIPURA Class 12-science Physics Electromagnetic Waves
Characteristics of EM Waves
1. An electromagnetic wave consists of oscillating electric and magnetic fields.
2. These waves propagate in vacuum with a speed c.
3. The magnitude of perpendicular electric and magnetic fields are related by E =cB.
Electromagnetic Spectrum
An electromagnetic wave consists of oscillating electric and magnetic fields.
These waves propagate in vacuum with speed c.
In principle, electromagnetic spectrum extends over an infinite range of frequency.
