Do radio waves have the shortest wavelength?
First of all, your question is not worded all that well. When we speak of a wave, in this case an electromagnetic one (as opposed to one made of water perhaps), we tend to describe them quantitatively with certain numbers. One may speak of the frequency of the wave (measured in Hertz), the energy of a wave (in joules), or, in your case, the wavelength of a wave (in metres). The electromagnetic spectrum is usually taught to span from radio waves (waves with relatively large wavelengths and low frequencies) to gamma rays (waves with relatively small wavelenths and very high frequencies). The misunderstanding you seem to have is that the electromagnetic spectrum stops at radio waves. It does not. In theory, the electromagnetic spectrum is infinite and continuous. That is to say, there is no limit to how large a wavelength can be nor how small one can be. The electromagnetic spectrum susually stops at radio waves (with a typical wavelength ranging from 1 to 10 metres) because waves longer than these lose their practicality. In theory, they exist, but they simply are not as important to us than their shorter cousins!!! Just as a side note, "long waves" are said to have a wavelength of around order 10^3 metres (or just around the order of a kilometre). Theoretically, I can imagine it possible to have a wave with a wavelength as long as the universe itself! Of course, as I mentioned earlier, such waves are of little practical value to us. As a result, yes it does have the "longest" waves.
Explain why the energy of infrared waves is greater than the energy of radio waves?
The energy of infrared waves is greater than the energy of radio waves. This is because infrared waves has a smaller wavelength compared to radio waves. The smaller the wavelength, the higher the energy.
The main difference between a radio wave and a light wave is?
The difference between a radio wave and a x-ray is the fact that x-rays have a much higher frequency. Since higher frequency means more energy in electromagnetic waves, x-rays can be used for purposes such as taking photos of things inside the body. Radio waves are at a lower frequency and have a much longer wavelength. They are used in radio, television, and communication.
Are X-ray and gamma radiations similar to visible light or radio waves except for their higher energies?
X-rays, gamma rays, radio waves, and visible light are forms of electromagnetic radiation. Gamma rays are highest in energy compared to other electromagnetic radiations. Radio waves are least in energy in the whole electromagnetic spectrum.
Why does gamma radiation damage body cells but radio waves do not?
The energy of a electromagnetic wave increases as the wavelength decreases. Radio waves have a very long wavelength compared to gamma rays. Since gamma rays have so much energy, they can change molecules by "kicking out" electrons with their energy. Where as radio waves don't have enough energy to effect many compounds.
The lower the frequency of a sound wave the?
For electromagnetic waves:Speed(v)=frequency(f)*wavelength(lambda)ORwavelength(lambda)=speed(v)/frequency(f)Therefore, wavelength and frequency have an Inverse relationship this means that assuming speed remains constant if the wavelength increases (gets longer) the frequency will decrease.
A low energy electromagnetic wave would also have?
the lowest frequency Lester was here
What are two differences between the red and green electromagnetic wave in a rainbow?
The difference is the wavelength's of the two colors, Red is on the "right" end of the visible light spectrum and thus "bigger" wavelength about 640-700 nanometers while Green is more on the "left" side at around 500 nanometers.
Compare the frequency and energy of infrared rays to the frequency and energy of visible light?
Infrared waves are shorter than radio waves and longer than visible light waves.

What type of electromagnetic wave has the shortest wavelenght?
Gamma rays have the shortest wavelength compared to most of other electromagnetic radiation. Gamma rays have high penetrating power and are high in frequency. Exposure to this type of radiation can cause many health complications.
What kind of wave's wavelength compare to a cell?
a sound waves wavelength compares to a cell by comparing the waves one by the other. cells compared to wavelength are electromagnetic waves lol:)
How are frequency wavelength and color interdependent on each other?
Each colour has different wavelengths....For example: In VIBGYOR It is in the order of increasing wavelength i.e Compared to red violet is having the shorter wavelength..... The frequency and wavelength are related by the equation: In vaccum: frequency= c/wavelengthwherec is the velocity of light in free spaceWhereas in any medium,frequency= Velocity of light in that medium/wavelength So, it is clear from the formula that the wavelength and frequency are inversely proportional to each other.... As the wavelength changes with colour the frequency also changes according to that.............. If the frequency is high, the wavelength will be low and viceversa....
Does xrays have a lower frequency?
Compared to most forms of electromagnetic radiation, X-rays have a high frequency. Only gamma rays have a higher frequency.
Do xrays and gamma rays have higher frequencies than ultraviolet rays?
Because that term is the name we have given to electromagnetic radiation with the highest observed frequency. If they had lower frequency, then we would call them by another name. And if they're called by that name, then they must be rays of the highest observed frequency, all because that is how we have defined them.
A microwave and an x ray are traveling in a vacuum compared to the wavelength and frequency of the microwave the x ray has a wavelength that is shorter or longer?
. Longer, and a period that is longer
Between green light and red light which has a higher frequency?
Red light has a longer wavelength than blue light, (i.e. greater distance for one oscillation of red light compared to blue light) so there are less oscillations in the same period of time for red light, and thus red light has a lower frequency than blue light. More concisely: Wavelength = Wavespeed / Frequency , where wavespeed is constant So Frequency = Wavespeed / Wavelength Therefore as wavelength increases, frequency decreases. Make sense? Jack
