Short wave frequency has a shorter wave length. Frequency is defined as number of cycles per second. If you have shorter waves (measure from peak to peak) you can get more of these packed into one second, so the frequency is higher.

How does the frequency of radio waves compare with the frequency of visible light?
The radio wave part of the spectrum is very wide. The extreme ends are, roughly,15km ( used for communicating with submerged submarines)1 mm ( used for research, and possibly for radar)The visible spectrum covers only a 2:1 range of wavelengths. It is centred on the colour yellow, with a wavelength ~= 700nm.The very shortest of the radio waves is about 1000 times as long as yellow light.
What is the difference between long radio waves and short radiowaves?
Actually, they're not shorter, they're longer. Their radio wave length is 10^3, whereas visible light is 0.5*(10^-6). Take a look here for further proof: http://en.wikipedia.org/wiki/Electromagnetic_spectrum
What is the minimum wavelength of a radio wave?
Extra-low frequency radio waves can have wavelengths as long as 3.5 miles or more. The shortest wavelength is around 1 mm.
What is an radio frequency interference filter?
I assume you mean for something like a car. It can be as simple as a capacitor to as complex as total shielding for the engine. The need is because spark plugs put out a random collection of radio frequencies, in fact the first "radios" were just that: a kind of spark plug that ran short or long for dots and dashes. Everybody heard everybody else.
What is radio frequency receiver?
The definition of what it is, is actually in your question. It's a receiver that operates in the radio frequency spectrum. Anything that has a transmitter is said to transmit in radio frequency or `RF`. The term radio is short for radiotelegraphy, which has become generic over the years. Where does the radio frequency start? Technically, it' at 10,000 hz and higher. That's not to say that there's lower frequency transmitters (The U.S. Gov't uses 2 hz. to reach our submarines when they're under water, but that's more of an exception than the rule. The radio frequency spectrum can extend into the gigahertz range for things such as satellite communications, and as our technology advances, we could eventually see frequencies in the teraherts. So a radio frequency receiver is anything that will receive a a frequency in the radio frequency range. Hope this helps, Cubby
What are the forms of electromagnetic waves with the lowest frequency?
The spectrum has been arranged in the order of increasing fequency and is given as follows: Long waves, (waves produced during lightning) - LOWEST FREQUENCY Medium waves, short waves. All these come under common title Radio waves Mircro waves Infrared Visible Ultra violet X-ray Gama ray The lowest frequency is the LOng wave. Hope electromagnetic waves may be produced when thinking process continues. The frequency will be the least one.
A low energy electromagnetic wave would also have?
the lowest frequency Lester was here
What does AM and FM on the radio stand for?
Amplitude Modulation and Frequency Modulation. They are different methods of transmitting radio signals. AM is good for transmitting radio signals long distance FM is good for transmitting radio signals short distances but better quality
What is the relationship of color of light and frequency?
Each colour of visible light has a different frequency. Red has the lowest frequency, meaning it has a long wavelength. Purple has the highest frequency and has a very short wavelength. The order is: red, orange, yellow, green, blue, purple. I hope this helps you!
Are the wavelengths of high frequency sounds short or long?
Shorter the wavelength higher the frequency so naturally high frequency soundwaves are short
Red light is low energy and has long wavelengths?
Violet light has a short wavelength, high frequency, and high energy. Red light has a much higher wavelength than violet light.
Do radio waves have short or long wavelength?
Short wavelength
Does ROY G. BIV list colors from long wavelength to short wavelength or short to long wavelength?
The color of visible light with the longest wavelength is red; the color with the shortest is violet. So "ROY G. BIV" lists the colors from long to short wavelength. Just to confuse you, we'll also mention that it lists them from lowest to highest frequency.
Are radio waves healthy for humans?
not for a long time. they are not very harmful as they have a long wavelength and a low frequency.
What are the different speeds of the electromagnetic spectrum?
In terms of speed, every part of the electromagnetic spectrum, (radio waves, infra-red, ultraviolet), all travel at the same speed in a vacuum, the speed of light, which is 300,000,000 m/s approx. In terms of energy, the low frequency and long wavelength end of the spectrum, such as radio, have a low energy as opposed to the high frequency and short wavelength end, such as gamma rays.

Waves with long wavelength low frequency?
yes waves with long wavelengthhave low frequency also low energy.
