How does radiation change across the electromagnetic spectrum?
The amount of radiation changes across the spectrum.
If the frequency of an electromagnetic wave decreases what will the wavelength do?
It will become longer, and it will carry less energy, its also likely, that if the change or loss in frequency is enough, the radiation will become a different type of electromagnetic radiation in the spectrum like gamma to x-rays or visible light to infrared and so on.
What is the emission of electromagnetic radiation by an excited atom called?
Gamma radiation is high-energy photons emitted by a radioisotope.
Why does gamma radiation NOT change the type of atom?
Gamma radiation, which is a type of electromagnetic radiation, does not change the type of atom because it does not involve the transfer or exchange of particles. Unlike alpha and beta radiation, which involve the emission of particles from the nucleus, gamma radiation consists of high-energy photons that are released from the atomic nucleus. Therefore, it does not alter the composition or identity of the atom.
What factor causes the greatest change in gene pools?
Environmental factors cause the greatest change in gene pools. some of these factors are radiation,pollution,food supply,population,predators,and camouflage. Of these factors the most important to today's gene pool is radiation because it causes mutation in the chromosomes and can completely change an organism.
How does radiation change across the electromagnetic spectrum?
The amount of radiation changes across the spectrum.
How does the wavelength of electromagnetic radiation change as its frequency decreases?
It becomes longer
What causes an electromagnetic wave to be omitted?
An electromagnetic wave is emitted when there is a change of the atomic configuration.
What causes the change in pitch of an approaching train whistle?
sound is wavelengths, and wavelengths get compressed when coming to you (and stretched when going away). the closer the wavelengths, the higher the pitch!
What causes an electromagnetic wave be emitted?
The change of atomic configuration.
Do speed and wavelength and frequency change causes in electromagnetic waves?
no it doesnt you d*** head
Emission of gamma rays does not change the atomic number of a nucleus?
no, gamma rays are very high frequency electromagnetic radiation and are not protons or electrons as alpha and beta radiation are respectively.
What happens to molecules if they receive electromagnetic radiation?
They are excited and their energy increases and possibly ejects an electron and change their size and shape..They will often absorb part of the radiation; in that case, their energy will increase.
What could change the DNA sequence of genes?
electromagnetic radiation - ultraviolet, x-rays, gamma raysparticle radiation - alpha, beta, protons, neutrons, cosmic rayssome chemicalstranscription errorsgenetic crossoversretrovirusesetc.
If the frequency of an electromagnetic wave decreases what will the wavelength do?
It will become longer, and it will carry less energy, its also likely, that if the change or loss in frequency is enough, the radiation will become a different type of electromagnetic radiation in the spectrum like gamma to x-rays or visible light to infrared and so on.
How does the electromagnetic spectrum arrange different types of radiation?
Yes. The different types are determined by their wavelength. We have assigned 7 commonly-used names to the different wavelengths (although within each type, you can get more wavelengths, as it is a continuous scale). The names are, from long wavelengths to short: Radio Waves, Microwaves, Infrared, Visible Light (the one we can see with our eyes), Ultraviolet, X-rays, and Gamma Ways (γ-rays). Ultraviolet, X-rays and gamma rays are ionizing, which means they can add or remove electrons from atoms, which can change the way they react. This is why they are dangerous. Infrared, microwaves and radio waves are not ionizing. They have longer wavelengths and less energy. Radio waves can have wavelengths of hundreds of meters, and visible light has wavelengths on the order of nanometers.
Why is UV radiation penetrating though the skin a physical change?
Penetration of uv radiation is physical change as it happens physically but after penetration it also causes some chemical changes along with physical effects .
