How does electromagnetic radiation change as frequency increases?

If you relate to the magnitude of the Induced Voltage due to Change in magnetic field you would find that
Ui = - n * d phi / dt
while phi would be B * A
if you assume that B Is caused by a fluctuating current I = I0 sin(w t)
Ui would be
Ui = - n dB/dt *A
Ui = -n I0 sin(wt) w * A
where w is the angular velocity
w= 2pi/ T and 1/T = f
w = 2pi f
therefore
Ui = -n I0 sin (w t) 2pi A * f
We see that there is a linear relation ship Ui is proportional to f. So if you double frequency the induced Voltage doubles as well.
hope this helps

How does the wavelength of electromagnetic radiation change as its frequency decreases?
It becomes longer
If the frequency of an electromagnetic wave increases the speed of the wave does what?
If the frequency increases, the wavelength decreases. Wavelength lambda and frequency f are connected by the speed cof the medium. c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s. c can be light waves or electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f
What happens to an electromagnetic wave's frequency as it's wavelength decreases?
The product of (wavelength) x (frequency) of any wave phenomenon is alwaysthe same number ... the speed of the wave. So if wavelength changes, thenfrequency must change by exactly the same factor in the opposite direction,in order for their product to remain constant.
As the frequency of sound waves increases the wavelength of the sound dereases.?
That's a correct statement. Although you didn't ask a question, I'll go on and add to it: The frequency and wavelength of any wave phenomenon, not only sound, change in exact inverse proportion, so that their product is constant. That product is the speed of the wave.
As the speed of a particle increases does its associated wavelength increase or decrease?
The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.

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.
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.

How does energy associated with waves change as wavelength changes?
Using this equation will help you understand what is going on: E=hc/wavelength h and c are constants. As wavelength increases, energy decreases. This is why UV radiation (which has a very small wavelength) has more energy than visible radiation, and this is also why UV radiation causes damage to living things
How does radiation change across the electromagnetic spectrum?
The amount of radiation changes across the spectrum.
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).
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.
