What electromagnetic waves are we exposed to?
We are constantly exposed to multiple sources of electromagnetic waves in the environment, ranging from static fields (such as the earth’s magnetic field), via radio frequencies to sunlight.
What are some electromagnetic waves that we use everyday?
Behaviour and uses of electromagnetic waves
- Radio waves. Radio waves are used for communication such as television and radio.
- Microwaves. Microwaves are used for cooking food and for satellite communications.
- Infrared.
- Visible light.
- Ultraviolet radiation.
What are examples of ultraviolet waves?
Examples of Ultraviolet Waves
- Disinfectants. Ultraviolet radiations are capable of killing bacteria and viruses.
- Water Purification.
- UV Lamps.
- Production of Vitamin D.
- Sterilization.
- Cure Skin Disorders.
- Tanning.
- Astronomy.
Are cosmic rays electromagnetic waves?
Cosmic rays are not electromagnetic radiation since they are high energy outer space particles. But β-ray is also not really an electromagnetic radiation because they are charged particles formed during β-decay. And hence B-ray is concluded as an electromagnetic radiation and cosmic ray is not.
How are radio waves used today?
radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. They are used in standard broadcast radio and television, shortwave radio, navigation and air-traffic control, cellular telephony, and even remote-controlled toys.
What type of wave is a electromagnetic wave?
EM waves are ‘transverse’ waves. This means that they are measured by their amplitude (height) and wavelength (distance between the highest/lowest points of two consecutive waves). The highest point of a wave is known as ‘crest’, whereas the lowest point is known as ‘trough’.
What is ultraviolet electromagnetic spectrum?
UV (Ultraviolet) Light refers to the region of the electromagnetic spectrum between visible light and X-rays, with a wavelength falling between 400 and 10 nanometers.
What are 10 examples of electromagnetic radiation in everyday life?
10 Examples Of Electromagnetic Radiation In Everyday Life 1 Visible Light Waves. 2 Radio Broadcasting Waves. 3 Cell Phone Radiation Waves. 4 Wifi and Bluetooth Waves. 5 TV Broadcasting Waves. 6 (more items)
What happens if you are exposed to radio waves?
Long-term exposure increases thermal radiation and may trigger headaches, vision problems, sleep disruption and even memory loss. Radio waves are also the lowest frequencies in the electromagnetic spectrum, and stars, lightning, and sparks often produce them.
What is the most dangerous form of electromagnetic waves?
Gamma rays: These are the most energetic and dangerous form of electromagnetic waves. Gamma rays are a type of harmful radiation. Typical size: 0.000001 nanometers (the width of an atomic nucleus). Photo: Diagram of electromagnetic spectrum courtesy of NASA.
How do electromagnetic waves affect our daily lives?
They help us communicate, cook, and even solve complex medical issues. From the radiation produced by your mobile phone to that derived from X-ray check-ups and airport control, electromagnetic waves seem to be ever-present in everyday life.
