Research and write a short description (3-4 paragraphs) of one of the following parts of the electromagnetic spectrum. Your desc
ription should include the wavelength, a brief description of what we know about the wavelength and how we use it (if we do!), or how it is harmful (if it is!) in our modern-day life. Radio Waves
Microwaves
Infrared Waves
Ultraviolet Waves
X-rays
Gamma Rays
Gamma rays have the highest energy radiation and have the smallest wavelength in the electromagnetic spectrum. They are formed by the hottest and most energetic objects in the world, with nuclear explosions, lightning and far less radioactive decay activity producing gamma rays. It can be both useful and dangerous, gamma rays are used in medicine to treat cancer with radiation when exposed to them, radiology, sterilization and much more.
Gamma rays have the highest energy radiation and have the smallest wavelength in the electromagnetic spectrum. Gamma rays are ionizing electromagnetic radiation, obtained by the decay of an atomic nucleus. Gamma rays are more penetrating, in matter, and can damage living cells to a great extent. Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry.
The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.
The manufacturer of a 9V dry-cell flashlight battery says that the battery will deliver 20 mA for 80 continuous hours. During that time the voltage will drop from 9V to 6V. Assume the drop in voltage is linear with time. How much energy does the battery deliver in this 80 h interval?
