electromagnetic radiation | Spectrum, Examples, & Types
UV radiation is a form of radiation that comes from the sun and is present in sunlight. It falls within the electromagnetic spectrum and has shorter wavelengths than visible light. Overexposure to UV radiation can have harmful effects on human skin, such as sunburn and an increased risk of skin cancer.
UV (Ultraviolet) radiation is a type of electromagnetic radiation produced by the sun. It is known for causing sunburn and skin damage. UV radiation can be harmful to living organisms, including humans, if overexposure occurs.
On 11 February 1800, (William) Herschel ... discovered infrared radiation in sunlight by passing it through a prism and holding a thermometer just beyond the red end of the visible spectrum... He was shocked when it showed a higher temperature than the visible spectrum. Further experimentation led to Herschel's conclusion that there must be an invisibleform of lLIGHT beyond the VISIBLE SPECTRUM.source:WikipediaWhite light is actually not a single colour. It is made up of lots of colours. The colours that you can convince yourself of seeing are red, orange, yellow, green, indigo, blue and violet. Each of these colours is actually a transverse wave. Becasue we can see them, we call this 'mini collection' of waves the 'visible spectrum'. Here's the note sheet on these 'visible' waves:The Waves of the Visible SpectrumSo, this is what Herschel did:Then, we tried it in the lab and here's the photo. The stick thing is a thermometer probe. We checked out the temperatures in the spectrum made by splitting white light with a 60° prism. Then we looked at the temperatures outside what we can see (to the left of the red in the photo).Repeating Herschel's experiment in the labAnd, much to our surprise, more than half of the class reported a higher temperature outside of the red part of the spectrum. If this is correct, we repeated Herschel's experiment in our lab. This 'unsee-able' colour is in fact a wave that we call today 'infra red'.The Electromagnetic Spectrum2.2 Demonstrate an understanding that all electromagnetic waves are transverse and that they travel at the same speed in a vacuum 2.3 Describe the continuous electromagnetic spectrum including (in order) radio waves, microwaves, infrared, visible (including the colours of the visible spectrum), ultraviolet, X-rays and gamma rays2.4 Demonstrate an understanding that the electromagnetic spectrum is continuous from radio waves to gamma rays, but the radiations within it can be grouped in order of decreasing wavelength and increasing frequencyElectromagnetic dangers2.5 Demonstrate an understanding that the potential danger associated with an electromagnetic wave increases with increasing frequency 2.6 Relate the harmful effects, to life, of excessive exposure to the frequency of the electromagnetic radiation, including:microwaves: internal heating of body cellsinfrared: skin burnsultraviolet: damage to surface cells and eyes, leading to skin cancer and eye conditionsX-rays and gamma rays: mutation or damage to cells in the bodyUsing the Electromagnetic Spectrum2.7 Describe some uses of electromagnetic radiation radio waves: including broadcasting, communications and satellite transmissionsmicrowaves: including cooking, communications and satellite transmissionsinfrared: including cooking, thermal imaging, short range communications, optical fibres, television remote controls and security systemsvisible light: including vision, photography and illuminationultraviolet: including security marking, fluorescent lamps, detecting forged bank notes and sterilising waterX-rays: including observing the internal structure of objects, airport security scanners and medical X-raysgamma rays: including sterilising food and medical equipment, and the detection of cancer and its treatmentIonising radiation2.8 Recall that ionising radiations are emitted all the time by radioactive sources 2.9 Describe that ionising radiation includes alpha and beta particles and gamma rays and that they transfer energy
Cosmic background radiation is the remnants of the Big Bang, the event that marked the beginning of the universe. It provides valuable information about the early conditions of the universe, helping us understand its formation and evolution. The uniformity and patterns in cosmic background radiation inform us about the distribution and structures of matter in the early universe, contributing to our understanding of its evolution over time.

UV radiation is a form of radiation that comes from the sun and is present in sunlight. It falls within the electromagnetic spectrum and has shorter wavelengths than visible light. Overexposure to UV radiation can have harmful effects on human skin, such as sunburn and an increased risk of skin cancer.
All types of cameras, pinhole and those using optical lenses, use light which is an electromagnetic radiation
The electromagnetic spectrum is a range of all possible frequencies of electromagnetic radiation. Light, the waves commonly referred to, falls within a specific region of this spectrum, primarily in the visible spectrum. This includes wavelengths of light that our eyes can detect, ranging from approximately 400-700 nanometers.
UV (Ultraviolet) radiation is a type of electromagnetic radiation produced by the sun. It is known for causing sunburn and skin damage. UV radiation can be harmful to living organisms, including humans, if overexposure occurs.
Light is a form of electromagnetic radiation that can be seen by the human eye. It is a type of energy known as radiant energy.

The microwave oven utilizes electromagnetic radiation to heat and cook food quickly and efficiently. This technology is based on scientific principles related to the interaction between microwave energy and water molecules in food, causing them to vibrate and generate heat. This process demonstrates scientific concepts such as electromagnetic waves and molecular motion.
Yes.
it relates to radiation because they contain electrons which is radiated
Blackbodies are objects that absorb all incoming radiation and emit it as thermal radiation. They have properties like perfect absorption and emission of radiation at all wavelengths. Examples of blackbodies in nature include stars like the Sun and objects at high temperatures like lava. These natural blackbodies help us understand concepts like thermal radiation and the behavior of light in the universe.
Microwaves are a type of electromagnetic radiation with wavelengths longer than infrared light but shorter than radio waves. In the field of physics, microwaves are studied for their properties and interactions with matter. They are used in various applications such as communication, cooking, and medical imaging, and play a significant role in understanding the behavior of electromagnetic waves.
