Radio waves are the longest, then Microwaves, infrared, Ultra Violet (UV), X-rays, Gamma Rays are the smallest.
The longest electromagnetic waves are those of the low audio frequency, and since these can penetrate sea water, these are used for submarine communication. But at a very low information rate.
[The shortest e-m waves are those of gamma radiation, particularly those of gamma ray bursts (GRB) which originate outside our galaxy. ]
The part of the electromagnetic spectrum with the lowest frequency and longest wavelength is radio waves. They are used for communication, broadcasting, and radar.
Gamma rays have the shortest wavelength in the electromagnetic spectrum.
The EM spectrum is a chart of electromagnetic radiation, arranged by wave length. The chart may be arranged in ascending or descending order.Related Information:The charts could begin with radio waves, having the longest wavelength, and end with gamma rays, having the shortest wavelength or the order could be reversed.
Shortest wavelength corresponds to highest energy, and this region of the EM spectrum contains high energy radiation such as X-rays and gamma rays.The part with the highest frequencies ... the end where the gamma rays are.
Visible light is a subset of the electromagnetic spectrum. Starting at the longest wavelengths (lowest frequencies), the electromagnetic spectum includes:Radio wavesMicrowavesInfra-redVisible lightUltravioletX-raysGamma raysRefer to the related link below for additional informaiton.

Radio waves are the longest of the E-M spectrum. The VLF (very low frequency) part of the radio spectrum is the longest usable part of that spectrum. This goes down to about 10kHz, and these low frequencies are used to communicate with submerged submarines.
The peak wavelength emitted by the Sun falls in the visible spectrum, specifically in the green part of the spectrum around 500 nm. This is why the Sun appears yellow-white to our eyes.
Our eyes can see the visible light part of the electromagnetic spectrum, which ranges from about 400 to 700 nanometers in wavelength. This includes colors like red, orange, yellow, green, blue, and violet.
Light with a wavelength of 489 nm falls within the blue region of the visible spectrum. It is part of the visible light spectrum. Light with a wavelength of 987 nm falls within the infrared region of the electromagnetic spectrum.
Visible light occupies the middle position in the electromagnetic spectrum, between infrared and ultraviolet radiation. This part of the spectrum is the only range of electromagnetic waves that can be detected by the human eye.
The second longest wavelength in the absorption spectrum of hydrogen corresponds to the transition from the n=2 to n=4 energy levels. This transition produces a spectral line known as the H-alpha line, which falls in the red part of the visible spectrum at a wavelength of 656.3 nm.
