Chapter U5.116, Problem 1TAI

Interpretation Introduction

Interpretation:

How the electromagnetic radiations can be measured needs 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 1TAI

An EMF meter is the only scientific instrument for measuring the electromagnetic radiation.

Explanation of Solution

Low frequency radiation meter is the device that can measure electric and magnetic field from electrical and electronic devices like power cables, transformer, etc.High frequency radiation meter is the device that can measure electromagnetic fields from cell phone, wireless internet,cordless phone,Bluetooth devices, alarm system,microwave ovens,wireless game TV, radio, broad casting, antennas, radars, police communication, etc.It can be measured in terms of energy,wave-length, frequency, etc. The frequency is measured in Hertz.

Conclusion

Electromagnetic radiation is not visible to human eye but it can be measured by an EMF meter.
