The wave with the lowest frequency ... the smallest number of MHz ...
would have the longest wavelength.
Have you ever noticed how sometimes, when you're out in the country and
you drive under a high-voltage electric line, there's this loud BUZZZ on the
radio for just a second, while you're exactly under the line ?
That's caused by the electromagnetic wave that the power line radiates. Its
wavelength is about 3,107 miles, and its frequency is 0.00006 MHz (60 Hz).
Radio waves have the longest wavelength in the electromagnetic spectrum.
The longest possible wavelength of a standing wave on a string that is 2 m long would be twice the length of the string, which is 4 m. This occurs when there is only one antinode (half a wavelength) present on the string.
Red has the longest wavelength in the visible spectrum of light.
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.
The type of wave that has the longest wavelength and lowest frequency is a radio wave. These waves are used for communication and broadcasting due to their ability to travel long distances.
Radio waves have the longest wavelength in the electromagnetic spectrum.
The electromagnetic waves with the longest wavelengths are called radio waves. There is no upper limit as to how large the wavelength can get; for example, you might imagine an electromagnetic wave with a wavelength as large as the diameter of our galaxy. That would still be called a radio wave.
In the electromagnetic spectrum, it is the radio wave that has the longest wavelength. Some radio waves are over 100 yards long.
Radio waves are the electromagnetic waves with longest wavelength.
From that list, microwaves have the longest wavelength. Those four items would be arranged by wavelength like this: - Gamma ray (shortest) - X-ray - Visible light - Microwave (longest)

The visible light with the longest wavelength is the last coloryou can see on the red end of the spectrum.
