Chapter U5.115, Problem 1E

Interpretation Introduction

Interpretation:

Electromagnetic radiations need to be explained.

Concept introduction:

Electromagnetic radiations are the waves of the electromagnetic field propagated throughout the space. It consists of radiant energy including microwaves, radio waves, infrared, ultraviolet rays, visible light,gamma rays and X-rays.

Answer to Problem 1E

Electromagnetic waves are oscillating at the electric and magnetic field to create easy propagation.In the vacuum the speed of electromagnetic wave is similar to the speed of light that is $3\times {10}^{8}m/s$ .These waves are emitted by electrically charged particles which accelerate and propagate with interaction of other charge particles and exert force on subsequent particles.

Explanation of Solution

Short term exposure to high level electromagnetic radiation is fatal to Human health but low level electromagnetic rays are not harmful to the health.Electromagnetic radiations are high frequency radiations used in modern technology for communications in variety of sectors.Electromagnetic radiation are used in Modern technology in FM radio, cord less and cellular phone,radar, micro ovens, etc. These instruments are used to transmit data and signal via electromagnetic waves.

Conclusion

Electromagnetic radiation is the disturbance of electric and magnetic field. It travels with the speed of light with no mass and charge.
