What are the effects of electromagnetic radiation on matter?
The main effect radiation has on matter is its ability to ionize atoms to become ions, a phenomenon known as ionization, which is very similar to the photoelectric effect. Radioactive particles or electromagnetic waves with sufficient energy collide with electrons on the atom to knock electrons off the atom.
What is an example of how electromagnetic energy can cause changes in matter?
Give an example of how electromagnetic energy can cause changes in matter. A microwave oven can change a frozen block of spaghetti and sauce into a hot meal—a physical change. The energy of electrically charged particles moving from one place to another.
What are the three ways electromagnetic radiation interacts with matter?
When photons run into atoms and molecules, there are three fundamental ways in which they interact with the matter: absorption, reflection, and transmission.
How does radiation absorb matter?
In physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon’s energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy).
Which type of radiation interacts strongly with matter?
Alpha Radiation Due to their charge and mass, alpha particles interact strongly with matter, and only travel a few centimeters in air.
What is the energy of moving matter?
Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The kind of motion may be translation (or motion along a path from one place to another), rotation about an axis, vibration, or any combination of motions.
Can electromagnetic radiation interact with matter?
Electromagnetic radiation (EMR) is energy that propagates through vacuum (free space) or through material media in the form of an advancing interaction between electric and magnetic fields. It can make itself manifest by its interaction with matter.
How does electromagnetic radiation affect matter when absorbed?
When electromagnetic radiation is absorbed by a bound charged particle, it can give the particle enough energy to set it free. An electron can be freed from an atom, a molecule, or from the energy band of a solid.
What is radiation interaction with matter?
If very energetic radiation interacts with matter, it causes a large number of processes involving energy transfer to other particles and the development of other particle forms, which in turn also interact with matter. This can lead to an electron positron pair that can produce braking X-rays, etc.
What kind of wave travels through matter?
A wave that can travel only through matter is called a mechanical wave. Mechanical waves travel through solids, liquids, and gases. Mechanical waves cannot travel through a vacuum.
Why do waves not transfer matter?
In a wave phenomenon, energy can move from one location to another, yet the particles of matter in the medium return to their fixed position. A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position.
