What are the 7 types of radiation?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
What are the 7 types of electromagnetic waves?
The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
Can TV give you cancer?
A new study links prolonged sitting while viewing TV to a higher risk of young-onset colorectal cancer, regardless of obesity and exercise. Recent research has linked prolonged sitting while viewing TV to a raised risk of developing colorectal cancer before the age of 50 years.
Is radiation from TV harmful?
Is the TV Radiation a Hazard? … It should be emphasized that most TV sets have not been found to give off any measurable level of radiation, and there is no evidence that radiation from TV sets has resulted in human injury.
Does Smart TV have radiation?
Smart TVs May Create an EMF Hazard
This is the same as with any electronic equipment that connects to a network. If you want a wireless connection, you will be exposed to high levels of radio-frequency electromagnetic radiation.
What is the most important electromagnetic wave?
The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.
What color has highest frequency?
What is electromagnetic radiation in simple words?
Electromagnetic radiation, in classical physics, the flow of energy at the universal speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves, visible light, and gamma rays.
What are the 2 types of radiation?
There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.
What are 4 examples of radiation?
- ultraviolet light from the sun.
- heat from a stove burner.
- visible light from a candle.
- x-rays from an x-ray machine.
- alpha particles emitted from the radioactive decay of uranium.
- sound waves from your stereo.
- microwaves from a microwave oven.
- electromagnetic radiation from your cell phone.
