How do you know the speed of a electromagnetic wave in a vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.

Why is wavelength all you need to know to calculate EM wave frequency in a vacuum?
Because the speed of light in a vacuum is constant(c). hence the formula, v=f.w, where v is velovity, f is frequency and w is wavelength, can be used to calculate the frequency.
What determines the radiation that an electromagnetic wave emits?
You're probably thinking of frequency and wavelength. If that's true, then you onlyneed one or the other. They're tightly connected, so if you know one of them, thenyou can always calculate the other one.
Is a vacuum still a vacuum if there are electromagnetic waves in the vacuum?
Yes, a vacuum is still a vacuum if electromagnetic waves are present. A vacuum is an area with no matter in it. We know that matter is anything which has mass and takes up space. Electromagnetic waves have no mass, and certianly take up no space. They're energy.
If you know the vacuum wavelength of any form of electromagnetic radiation you can determine its frequency because?
You know its speed in vacuum, and frequency = (speed) / (wavelength) .

What is meant by vacuum wavelength?
Vacuum wavelength is the wavelength that is measured if the wave is passing through a vacuum. To get the wavelength in a medium you need to know the refractive index.

How do you find velocity when only the frequency is given?
The question is incomplete. Frequency of what? If it refers to electromagnetic waves, you won't need even frequency to determine velocity (in a vacuum), because it will always be c (the speed of light). You can compute the speed of other kinds of waves if you know the frequency and wavelength, but not from frequency alone. The formula is frequency x wavelength = velocity If the waves are electromagnetic, and you have only frequency, you can compute the wavelength using the same formula.
How do you calculate the amplitude given the frequency and the wavelength?
Amplitude doesn't depend on frequency or wavelength, so even if you know them, you have no way to calculate amplitude.
Which property is the same for all forms electromagnetic radiation?
The speed (in a vacuum) is the same for all electromagnetic radiation.The speed (in a vacuum) is the same for all electromagnetic radiation.The speed (in a vacuum) is the same for all electromagnetic radiation.The speed (in a vacuum) is the same for all electromagnetic radiation.
What is the formula to calculate the diameter of a string to get the desired Hz if you know the wavelength?
There is no such formula.
