There are many types of electromagnetic radiation, ranging from the high-energy radiation of X-rays and gamma rays, to the lower-energy radiation of radio waves and microwaves. These different types of radiation are characterized by their wavelength, or the distance between successive wave crests. The shorter the wavelength, the higher the energy of the radiation.
Which of these is not a form of electromagnetic radiation? While all of the above-mentioned types of radiation are forms of electromagnetic radiation, ultraviolet (UV) light is not.
UV light is often confused with other forms of electromagnetic radiation because it shares some characteristics with them. Like other forms of electromagnetic radiation, UV light is made up of electromagnetic waves. These waves are produced when an atom or molecule absorbs energy and then re-emits it. The wavelength of UV light is shorter than that of visible light, making it invisible to the human eye. However, UV light can be detected by some insects, which is why it is sometimes called "black light."
Unlike other forms of electromagnetic radiation, UV light does not have enough energy to ionize atoms or molecules. This means that UV light cannot break apart chemical bonds or cause atoms to gain or lose electrons. For this reason, UV light is not harmful to human tissue in the way that X-rays or gamma rays are. However, UV light can still damage DNA, leading to skin cancer.
So, while UV light is a type of electromagnetic radiation, it is not harmful in the same way as other forms of electromagnetic radiation. This is because UV light does not have enough energy to ionize atoms or molecules.
Frequently Asked Questions
Is electromagnetic radiation isotropic or homogeneous?
Electric and magnetic fields are both homogeneous in their distribution throughout the medium, but they are not isotropic. Electric and magnetic waves propagate in all directions with the same speed, and their wavefronts form a sphere.
Why are cathode-rays not considered as electromagnetic radiation?
Cathode-rays are beam of electrons and therefore they do not contain photons which is one of the characteristic of electromagnetic radiation.
What are some examples of electromagnetic radiation?
Some examples of electromagnetic radiation are: light, radio waves, microwaves, infrared waves, gamma rays, x-rays and ultraviolet waves. Harmful effects of visible light waves include: Sunburns, cancerous cells growth from exposure to the sun's UV radiation, eye damage from looking at the sun too long and skin cancers. 2. Radio Waves Radiation Next on our list is radio waves! Similar to visible light waves, this type of electromagnetic radiation derives from what our ears perceive as sound. What are some examples of electromagnetic radiation? Some examples of electromagnetic radiation are: AM radio waves, FM radio waves and TV waves. Harmful effects of radio waves include: headaches and nausea from strong signals; interference with electronic equipment; problems with cell phones reception; and being tracked by government intelligence agencies. 3. Microwaves This type of electromagnetic radiation is created when energy travels through the airwaves at frequencies higher
What are the two types of electromagnetic waves?
Non-ionizing radiation: these waves are unable to break the chemical bonds in molecules, and therefore have little or no potential to cause damage. They can include radio waves, microwaves, infrared, and visible light. Ionizing radiation: these waves can break chemical bonds, which means they have the ability to damage cells. They include ultraviolet (UV), X-rays, and gamma rays.
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of radiation that a substance emits or absorbs and can be broken down into radio wave, visible light, and gamma ray radiation.
