radiation is produced by the Sun's UV rays. (UV means Ultra violet). They are sometimes harmless, because radiation is everywhere. But too much exposure can cause harm to you.
wow really hahah it most likely is in your science book! :p that was a dumb question! lol no offense....
In a simple sentence explain infrared radiation.
Radiation refers to the emission of energy in the form of particles or electromagnetic waves. It can come from various sources, both natural and man-made. To understand what radiation is, let's break it down further:
1. Particles: Radiation can consist of tiny particles, such as alpha particles, beta particles, or neutrons. These particles are emitted by certain types of matter during radioactive decay.
2. Electromagnetic Waves: Radiation can also take the form of electromagnetic waves, including gamma rays, X-rays, ultraviolet (UV) rays, visible light, infrared (IR) rays, microwaves, and radio waves. These waves have different properties and energy levels, with gamma rays being the most energetic and radio waves being the least energetic.
Understanding radiation involves considering its sources, such as:
1. Natural Sources: Radiation is naturally present in our environment. For example, the sun emits UV rays, visible light, and other forms of electromagnetic waves. Radioactive materials found in rocks, soil, and even our bodies can also contribute to natural radiation exposure.
2. Man-made Sources: Human activities can also generate radiation. Medical procedures that involve X-rays, radiation therapy for cancer treatment, and nuclear power generation are examples of man-made radiation sources.
To learn more about radiation, you can study different sciences like physics, chemistry, and biology. These fields provide a deeper understanding of radiation, its properties, and how it is detected, measured, and its potential effects on living organisms.
