Electromagnetic radiation

There are three main heat transmitters, they are conduction, convection and radiation. Conduction of heat occurs when molecules increase in kinetic energy, the molecules vibrate and this vibration passes the heat to the surrounding molecules. Conduction only occur in solids. Convection is a type of heat transfer that only occurs with liquids and gases because it involves the liquids and gases physically moving, which a solid is unable to do. Convection happens when there is a difference in…

really out there, thanks to advances in electromagnetic radiation detection it is now possible for humans to study the universe in depth to develop theories such as a heliocentric model of the universe instead of the earlier believed geocentric model. Humans have also been able to observe never before seen phenomena such as the effects of black holes. The national aeronautics and space administration (NASA) are responsible for many of the advances in electromagnetic detection technology advances…

increased significantly since their first arrival over four decades ago in 1973. Cell phones transmit and receive radio-frequency electromagnetic waves which are the weakest waves in the electromagnetic spectrum with the lowest frequency but the biggest wavelength in the spectrum. This type of electromagnetic radiation is less dangerous than higher frequency electromagnetic radiation at immediate contact as it is non-ionizing however there has been debate over the long term effects of…

of a cluster of galaxies called the Local Group. Astronomers use different wavelengths of electromagnetic radiation to measure celestial objects. Special telescopes are designed to measure different electromagnetic radiation, some include: radio telescopes, infrared telescopes, visible telescopes, and ultra violet telescope. Each type of telescope specializes in measuring different wavelengths of radiation, which is very helpful as different celestial objects emit different…

Little to no precipitation can cause drought. Many native plants go through a process called thermoperiodism because Kansas experiences different periods of extreme weather. Plants in Kansas tend to be tolerant of most conditions, some more than others. There are drought resistant plants located in the park, shown in the table made by Holly Dickman shows a list of drought tolerant plant materials found in northwest Kansas. Although the site is in northeast Kansas, the plants do not vary enough…

Why we get sunburned A suntan is the result of the body’s defense mechanism against harmful ultra violet light emitted by the sun. All bands of UV radiation damage collagen fibers and accelerate aging of the skin. Both UVA and UVB destroy vitamin A in skin, which may cause further damage. UVB light can cause direct DNA damage. In defense, our body releases a pigment called melanin, which is produced by cells in our skin called melanocytes. Melanin absorbs ultraviolet light and dissipates it as…

While cookies are baking in the oven, heat transfer occurs to make them bake correctly. As said by the author Nora Fulmer, heat transfer is the process where an item comes into contact with a heat source and exchange thermal energy between two objects. It is a complex process that removes bacteria, while cooking food. Heat energy is created and transferred when food becomes hot, its molecules absorb energy and begin bouncing off each other. The first type of heat transfer is conduction.…

Neutron Imaging In physics, radiation is described as the transmission or emission of energy in the form of particles such as electrons, neutrons, protons and alpha particles or waves through a medium such as space, air or through a material. Gamma radiation (γ) and electromagnetic radiation, such as x-rays, radio waves heat and visible light are all examples of radiation. One of the main modern physics discoveries was that each unit of a wavelength of any form of wave radiation will carry more…

Introduction The purpose of this lab is to find the most efficient way to capture energy from a combusted chip using a calorimeter. We made a basic calorimeter by using a steel can. Through out our lab we made modifications to the calorimeter to increase the percent of energy captured by the water. Literature Review Kinetic energy is the energy of motion. The kinetic energy of an object is energy that is being used. Potential energy is stored energy that it is not in motion, but has…

a lot of stars cannot be seen by the naked eye, a radio telescope is used that detects the radiation. Electromagnetic energy describes the different kinds of energies released into space by stars such as the Sun. They include: Radio waves, TV waves, Radar waves, Infrared radiation (heat), Light, Ultraviolet light, X-rays, Short waves, Microwaves, Gamma rays. However, all kinds of electromagnetic radiation, like harmful gamma rays, are released from the Sun, our atmosphere stops some kinds from…
