ELECTROMAGNETIC SPECTRUM CELL 3

WHAT IS ELECTROMAGNETIC SPECTRUM? E lectromagnetic spectrum refers to a broad range of radiation that consist of different types – radio waves, microwaves, infrared waves, visible light, ultra-violet rays, x-rays and gamma rays. These waves have a variety of applications and characteristics according to their wavelengths and frequencies. Electromagnetic waves are radiations in the form of heat, light and electromagnetic energy. They are created when electric charges accelerate, carry radiant energy or radiation that affects living organisms and the environment.

IO WA DAR SEV DESCRIPTION Radio waves are electromagnetic waves that are invisible to t he human eye. USES These waves are commonly used in communication. Like cellphones and talking. PRACTICAL USES TODAY With the use of radio waves, talking or communicating h ave been easy. INTERACTION WITH MATTER Radio waves' interaction with matter is through air because they propagate in the air. EFFECTS TO LIVING ORGANISMS AND THE ENVIRONMENT Radio waves may benefit us; but it also contains radiation that can be harmful. Overexposure to these can cause damage to cells and tissues

CROWAV IM SE DESCRIPTION Microwaves are a form of \"electromagnetic\" radiation; that is, they are waves of electrical and magnetic energy moving together through space. USES Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes. PRACTICAL USES TODAY Microwaves are widely used in everyday technologies such as communication, Wi-Fi, and food heating. INTERACTION WITH MATTER Microwaves interact with matter through its constituent atoms, conduction electrons if present, and atomic magnetic dipoles if present, microscopically. Because microwaves cause electric dipoles to execute damped oscillations at the GHz frequency, they absorb a lot of them. EFFECTS TO LIVING ORGANISMS AND THE ENVIRONMENT A large number of studies have shown that microwave radiations can cause a series of adverse reaction in the central nervous system, including sleep disorders in addition to learning and memory impairments.

ARED WA RFNI SEV DESCRIPTION These waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less USES scattering and absorption It can be used in electrical heaters, cookers for cooking food, short- range communications like remote controls, optical fibers, security systems, infrared astronomy and thermal imaging cameras which PRACTICAL USES TODAY detect peo ple in the dark. used to heat up ob j ects or cook Mainly food INTERACTION WITH MATTER This can be observed when organic or inorganic matter start to rise in their tempe rature EFFECTS TO LIVING ORGANISMS AND THE ENVIRONMENT Believed to be part of the greenhouse effect by absorbing the radiation from the sun’s rays and re-emitting them back out into the atmosphere. And is also believed to enhance cell regeneration by infrared therapy.

IBLE LI SIV THG DESCRIPTION Visible light is a form of electromagnetic (EM) radiation. Generally, visible light is defined as the wav elengths that are visible to most USES human eyes. Visible light has many applications and uses in our daily life. it helps us to see objects. Also visible light is used by plants in the pr ocess of photosynthesis. Visible light is also used in communication when it comes to transmitting signals and to replace telephone wires. Also it helps you to see colors and it shows the sequence of colors from longest to shortest wavelength called ROYGBIV stands for red, orange, yellow, green, blue, indigo and violet. Visible light is very helpful everywhere and anywhere, we can encounter visible light in traffic light, television, screen, devices and many more. PRACTICAL USES TODAY Sight INTERACTION WITH MATTE R Light interact either like a particle or a wave. When light behaves as a particle it undergoes absorption, scattering or pair production depending on atomic number and frequency of light. Ex. Sunlight EFFECTS TO ORGANISMS AND THE ENVIRONMENT Plants use visible light to power their photosynthetic cycle, which allows them to produce simple sugars from the elements in their environment.

AVILET R RTLU SYA DESCRIPTION Ultraviolet (UV) light or rays have shorter wavelengths than visible light. It is commonly subdivided into UV-A, UV-B, and UV-C. In 1801, Johann Ritter conducted an experiment to investigate the existence of energy beyond the violet end of the visible spectrum. USES is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. But they can also be used to get a sun tan, detecting forged bank notes in shops, and hardening some types of dental filling. PRACTICAL USES Mostly used in medicine to kill bacteria and to sanitize equipment INTERACTION WITH MATTER UV rays can make colors look faded or even bleach them if exposed long enough. EFFECTS TO ORGANISMS AND THE ENVIRONMENT Depending on the amount and form of the radiation exposed to the skin, as well as on the skin type of the individual exposed, ultraviolet radiation causes erythema, sunburn, photodamage (photoaging), photo carcinogenesis, damage to the eyes, alteration of the immune system of the skin, and chemical hypersensitivity. It also affects many processes connected with the carbon cycle. It inhibits photosynthesis in plants and algae, particularly phytoplankton which produce roughly half of the oxygen in the atmosphere.

X-RAYS

MMA RA AG SY DESCRIPTION Gamma rays are electromagnetic radiation that have the shortest wavelength but highest energy. They are emitted during nuclear reactions and their radiation has high penetrating power. USES These waves are used in medicine to eliminate cancerous growths, and bacteria when sterilizing instruments and also used to in studying the functions of organs. PRACTICAL USES Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry. INTERACTION WITH MATTER They interact with matter through ionization via three processes; photoelectric effect, Compton scattering or pair production EFFECTS TO ORGANISMS AND THE ENVIRONMENT Overexposure to thesewaves may damage living cells and cause radiation sickness and massive cellular damage.
