![]() The shortest waves, Gamma rays, are approximately 10 -12 m in wavelength. Gamma Rays can used in chemotherapy in order to rid of tumors in a body since it has such a high energy level. X-rays are used to produce medical images of the body. UV radiation is most commonly known because of its severe effects on the skin from the sun, leading to cancer. Ultraviolet, Radiation, X-Rays, and Gamma Rays are all related to events occurring in space. 7: The color regions of the Visible Spectrumįig. Thus, some colors are reflected more than other, leading to the creation of a rainbow.įig. Rainbows are formed in this way light passes through matter in which it is absorbed or reflected based on its wavelength. This part of the spectrum includes a range of different colors that all represent a particular wavelength. Visible Light is the only part of the electromagnetic spectrum that humans can see with an unaided eye. This picture represents a snap shot in mid-infrared light. Infrared Radiation is most commonly used in remote sensing as infrared sensors collect thermal energy, providing us with weather conditions. It can also be bounced back, which is called near infrared because of its similarities with visible light energy. Infrared radiation can be released as heat or thermal energy. Short microwaves are sometimes used in Doppler radars to predict weather forecasts. They are good for transmitting information because the energy can go through substances such as clouds and light rain. Microwaves can be measured in centimeters. They are also used in remote sensing in which microwaves are released and bounced back to collect information on their reflections. Microwaves can be used to broadcast information through space, as well as warm food. Especially useful in weather, radar systems are used to can illustrate maps of the surface of the Earth and predict weather patterns since radio energy easily breaks through the atmosphere. They are also used in radar systems, where they release radio energy and collect the bounced energy back. Radio waves are used in remote sensing, where hydrogen gas in space releases radio energy with a low frequency and is collected as radio waves. Radio waves have the lowest energy levels. As the name implies, radio waves are transmitted by radio broadcasts, TV broadcasts, and even cell phones. Radio Waves are approximately 10 3 m in wavelength. It is usually characterized by the Greek symbol \(\lambda\). Wavelengths are measured between the distances of either crests or troughs.The speed of light is always a constant.For example, sound waves need either a gas, solid, or liquid to pass through in order to be heard. Most other types of waves must travel through some sort of substance. Electromagnetic radiation can travel through empty space.General Properties of all electromagnetic radiation: These electric and magnetic waves travel perpendicular to each other and have certain characteristics, including amplitude, wavelength, and frequency. ![]() This energy is then grouped into categories based on its wavelength into the electromagnetic spectrum. Electron radiation is released as photons, which are bundles of light energy that travel at the speed of light as quantized harmonic waves. The electric and magnetic fields come at right angles to each other and combined wave moves perpendicular to both magnetic and electric oscillating fields thus the disturbance. ![]() \)Įlectromagnetic radiation is a form of energy that is produced by oscillating electric and magnetic disturbance, or by the movement of electrically charged particles traveling through a vacuum or matter.
