You need an electromagnetic wave...light, radio waves, microwaves, gamma rays, etc,. and ,in particular , electricity, where the term EMF (electric and magnetic fields) is more commonly used than the term EMR (electromagnetic radiation). Are you being asked to write about EMR and its possible health effects on humans? I'm just guessing, it cause some concern awhile back about causing certain cancers (also cell phone EMR was a concern), none of which has ever been proven, There's probably tons of literature available ..try a Google search.desormais said:Homework Statement
Sorry if this is the wrong place, I'm new here but I've been given a little paper to write on electromagnetic radiation. I am having trouble finding what the necessary conditions are for the emission of EMR, and kind of don't understand what it's really asking me for.
thanks in advance.
EMR stands for electromagnetic radiation, which is a form of energy that travels through space in the form of waves. It includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
The two main conditions necessary for the emission of EMR are the presence of charged particles and their acceleration. When charged particles, such as electrons, are accelerated, they create electromagnetic waves and emit EMR.
The wavelength of EMR is inversely proportional to its energy. This means that shorter wavelengths have higher energy and longer wavelengths have lower energy. For example, gamma rays have very short wavelengths and high energy, while radio waves have longer wavelengths and lower energy.
Yes, EMR can be emitted by non-luminous objects. Any object that has charged particles and is capable of accelerating them can emit EMR. This includes objects such as a charged particle accelerator, a television antenna, or even the human body.
The speed of EMR is constant and is approximately 3 x 10^8 meters per second, which is the speed of light. This means that all forms of electromagnetic radiation travel at the same speed in a vacuum.
