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 causes electromagnetic radiation to change its wavelengths?
Absorption and re-emission.
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.
When iron is heated until it turns red will the color show a chemical change has occurred?
Iron turning red happens when it is burnt and it is not called as rusting because rusting happens when iron material has not been used for a long time.Iron turning red is a chemical change because change in color is also considered as a chemical change.
How does energy change within the electromagnetic spectrum?
Heat energy

Do different colors of light change how hot or cold it is?
Visible light, the Red, Orange, Yellow, Green, Blue, Indigo, Violet colours of the rainbow are just a small part of the electromagnetic radiation spectrum which comprises electromagnetic waves of different wavelength. Beyond the red colour we can see is a part of the spectrum called infrared and heat - the warmth you feel when you hold out your hand towards a fire. Beyond the Blue/Violet colours we can see is a part of the spectrum called ultraviolet and it is this radiation that gives you sunburn.
What causes electromagnetic radiation to change its wavelengths?
Absorption and re-emission.
How does the wavelength of electromagnetic radiation change as its frequency decreases?
It becomes longer
What is another name for infrared?
Light waves are energy, and are a form of electromagnetic radiation. That makes them similar to radio waves (which have a lower frequency) and X-rays (which have a higher frequency).
How can different electromagnetic energy be distinguished?
Electromagnetic energy comes in two basic forms: 1. Ionising 2. Non-ionising Ionising radiation has the capacity for its photons to knock components off atoms and change their chemical constitution. This is a feature of electromagnetic radiation with a short wavelength, from the short-wavelength end of the visible spectrum downwards. Non-ionising EM radiation has a longer wavelength, that is most of the visible spectrum, infra-red, microwaves and radio waves. It has insufficient energy in the photons to modify atoms. This type can only damage living tissues if it is too intense, and the mechanism of the damage is by a temperature rise only.
Is electromagnetic spectrum and frequency spectrum same?
Electromagnetic waves have an associated frequency and wavelength. They are related by c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency. All electromagnetic waves travel at the speed of light. A change in frequency results in a change in wavelength (as required by the given equation). In short, yes. They're the same.
What is the relationship between wavelength and frequency in the elecrtomagnetic spectrum?
They are inversely related. The product of these two would give the velocity of electromagnetic wave in the medium. The frequency character would never change as the wave changes from one medium to the other. But as the speed changes then definitely its wavelength would change
What is the name for the change in the star's spectrum when it moves away from earth?
That is called "redshift". The frequency of the radiation decreases.
What is a field in the electromagnetic spectrum?
There are electric fields and magnetic fields. If those change over time, the changes may propagate at the speed of light - that's called an electromagnetic wave.
What are three forms of energy into which radiant energy can change?
The only possible form is via electromagnetic radiation, in the visible, infrared and ultraviolet sections of the spectrum. Cosmic ray particles also reach us but they can hardly be classified as energy
