Question

hey guys help me out in this topic:-


In wave nature of electromagnetic radiation

don't spam ...!!!

Answer 1

Heya....✋

⏩Besides the mechanical waves, there are waves which do not require any medium for their transmission. These waves are called Electromagnetic waves or Electromagnetic radiations. Radio waves, infrared waves, visible light, X-rays, ultraviolet rays gamma rays, etc are various types of electromagnetic radiations.

⏩Electromagnetic radiations is generated by oscillations of a charged body in a magnetic field or of a magnet, in an electric field. These radiations or waves have electric and magnetic fields associated with them and travel at right angles to these fields.

✨The following are important characteristics of electromagnetic radoations⤵

▶These consist of electric and magnetic fields that oscillate in directions perpendicular to each other and perpendicular to the direction in which the wave is travelling.

▶All electromagnetic radiations travel with same velocity,i.e., velocity of light.

▶The electromagnetic radiations do not require any material medium for transmission. For example, rays from the sun reach us through space which is a non-material medium.

Hope it helps dear✅
