What is the name for all the electromagnetic waves that exist? Names of the electromagnetic waves that exist are Gamma Rays‚ X-Rays‚ Ultraviolet Waves‚ Visible Light‚ Microwaves‚ and Radio Waves. 2. What are electromagnetic waves produced from? What two things do they have? Electromagnetic waves are produced by the vibration of charged particles and have electrical and magnetic properties. 3. What is the name for the section of the electromagnetic spectrum that we can see with our eyes

contribution of Hertz’s research is seen in radio telescopes. Since many interactions in the universe cannot be seen in the visible light part of the electromagnetic spectrum‚ various telescopes‚ such as the radio telescope‚ have been created to detect the effects of these events in other portions of the electromagnetic spectrum (Electromagnetic Spectrum). This is important for observing objects that cannot be seen by the human eye but can be indirectly observed through their effects on their surroundings

Ideas about the solar system Our understanding of the solar system has changed over many centuries. Scientists such as Ptolemy‚ Copernicus and Galileo added their ideas to our changing understanding. We observe the universe using a variety of equipment‚ from telescopes to orbiters and landers. Models of the solar system The planets and the Sun orbit the Earth in Ptolemy’s model. Our understanding of the universe has changed over time. Different civilisations have created different models to

A discussion of the regions (or bands or types) of the electromagnetic spectrum is given below. Note that there are no precisely defined boundaries between the bands of the electromagnetic spectrum; rather they fade into each other like the bands in a rainbow (which is the sub-spectrum of visible light). Radiation of each frequency and wavelength (or in each band) will have a mixture of properties of two regions of the spectrum that bound it. For example‚ red light resembles infrared radiation

Chapter 2 Review of Related Literature Electromagnetic is one branch of physics. It was concerned with magnetism produced by electric currents and with the interaction of electric and magnetic fields. Electromagnetism is defined the interaction between a magnetic field and an electric field. People use electromagnetic to transmit electricity to other place‚ to supply electricity form magnetic fields and to store and conserve energy. Electromagnet has components of strong interaction‚ weak interaction

Electromagnetic Spectrum Project Introduction: In this project you work for a company that produces and sells electromagnetic waves (Waves-R-Us). Your job is to do extensive research on the company’s products and then to design a catalog that will persuade customers to buy our product. You will also need to inform customers of the dangers of our waves. Task: You must design a catalog that will persuade the customers of Waves-R-Us to buy your products. Your catalog must have 1 page for each

Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum
