usage of electromagnetic spectrum

There are 7 different types of electromagnetic spectrums, which are Gamma rays, X-rays, ultraviolet rays, visible light, infrared, microwaves and radio waves. Each of them has their unique characteristics and if you use them carefully, it can be utilized to benefit people from many ways. In this essay, I will focus about Gamma rays, and Infrared lights.

Gamma ray was first discovered in 1900 by French physicist Paul Villard. When Villard found Gamma rays, he recognized it is different from X-rays that was discovered in 1896 because it had much deeper penetrating depth (NASA, 1998). Since then, scientists have researched about Gamma rays and found the way to use it efficiently. One of the examples of adapting Gamma ray in modern technology is cargo scanner. By using the characteristic of Gamma ray, scientists made super wide detector which can check 30 containers in one hour. The principle is same as security scanner in airports, but unlike X-rays, Gamma rays have deeper penetrating depth so it can see through deeper and much clear. This detector is very expensive, which is average 5,000,000 dollars, but even though it is very expensive, it’s economically efficient because some people secretly import stuffs such as drug, fire arms, and ivory in huge container which is extremely expensive compared to its size. Gamma rays can detect these drugs very easily because it has deep penetrating range. By stopping people from importing these drugs, it can socially benefit people because since it is hard to import drugs, the price will go up, and since people can’t afford high price, people won’t start drug, and it can reduce drug addicts

Gamma rays can also be used for sterilization. This technology shares same principle with radiotherapy...

...hey use sprinkler system when they really need it, when their plants almost die, but some farmers just wait for the rain and they miss the timing to give the water to their plants and they die. Also, after killing all the plants, farmer fall in anguish and might consider suicide, this is happening in middle east, so by using weather forecast using infrared light, we can reduce the economical and social damage by minimum.

To conclude each of the electromagnetic spectrums have their unique characteristics and used, and adapted to many other products and it is being used widely. These spectrums have significant impact in our society in moral, ethical, social, economic, political, cultural and environmental ways and we can’t continue living without them. If we develop and research about these topic more, it will help us to make our life more efficient and comfortable.
