something about the wavelengths that make up a particular type of radiation (i.e.‚ the spectrum of radiation)‚ one could use an object such as simple diffraction parallel-slit grating in the form of a spectrometer. For example‚ molecules‚ atoms‚ and nuclei typically radiate or scatter radiation that corresponds to discrete frequencies and hence discrete wavelengths‚ λ. Knowing the spectrum (the intensity and wavelengths) of these radiations can tell us a lot about the molecule‚ atom‚ and nucleus under

nuclear chemistry with medicine is the form of radiation. There are types of methods used to apply radiation to the human body to outline some they will be medical imaging (X rays) and radiation therapy which are in the emphasis of nuclear medicine. Also nuclear chemistry has some other methods that deals with nuclear medicine called analytic methods which are using radioactive isotopes for biological tracers and using isotopes for dilution. Radiation can have beneficial and harmful effects towards

Electromagnetic radiation (EM radiation or EMR) is a form of radiant energy‚ propagating through space via photon wave particles. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one another‚ perpendicular to each other and perpendicular to the direction of energy and wave propagation

phones transmit and receive Radio Frequency (RF) signals in order to communicate. The RF signals from [cell] phones fall within the microwave part of the electromagnetic spectrum. This radiation is also referred to as microwave radiation or electromagnetic radiation. In short: Cell phones use microwave radiation to communicate.

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
