Radio waves are the electromagnetic waves with longest wavelength.
X-rays have by far the shorter wavelength. Radio waves can go from several meters in length to miles in length. X-rays, on the other hand, have a wavelength of 0.01 to 10 nanometers. (Nanometers are one-billionth of a meter thick. For a better picture, think of a millimeter - and divide it into one million.)

Wavelength
The wave length and frequency of course vary, the frequency ranges from 3kHz to 300 GHz. The wavelengths are longer than infrared.
Radio waves are the electromagnetic waves with longest wavelength.
The ideal length for an AM radio antenna is typically around 1/4 of the wavelength of the radio waves being received, which is approximately 100 to 300 meters.
Radio waves have the longest wavelength in the electromagnetic spectrum, ranging from several meters to kilometers in length.
Any length longer than 1 millimeter would.
Radio waves have the longest wavelength among the electromagnetic spectrum, ranging from several meters to kilometers in length.
The answer depends on what the wave length is in ordinary numbers! For example, radio waves can have a wavelength of 1 metre: in scientific notation, that is 1!
The give-away should be the word "length" which is hidden in the word "wavelength". Wavelength has the dimensions of length, and is most often stated in meters or centimeters (radio), nanometers (light), etc.
The longest wavelength is radio waves, followed by microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, which have the shortest wavelength.
The longest wavelength is radio waves, which can range from several meters to thousands of kilometers. The shortest wavelength is gamma rays, which are typically less than 0.01 nanometers in length.
300 MHz: λ = about 3.278 feet.
X-rays have by far the shorter wavelength. Radio waves can go from several meters in length to miles in length. X-rays, on the other hand, have a wavelength of 0.01 to 10 nanometers. (Nanometers are one-billionth of a meter thick. For a better picture, think of a millimeter - and divide it into one million.)
Radio waves have the longest wavelength among the electromagnetic waves. They are used for communication and have wavelengths ranging from a few millimeters to hundreds of meters.
