... is an inherently meaningless term; no matter how long a wavelength you name, I can choose one that's longer ("infinity" is not a real wavelength, and for any non-infinite number, there's always a larger one).
Long-wave electromagnetic radiation used in special telescopes includes infrared radiation and submillimeter radiation. These telescopes are designed to detect and study objects that emit or reflect these longer wavelengths of light, allowing astronomers to observe phenomena such as cool stars, cosmic dust, and molecular clouds.
The electromagnetic waves with the longest wavelength are called "radio waves". There is no limit to how long the wavelengths can be.
Infrared is one, radio waves are another and many include microwaves as a third but microwaves are used for communications and are a form of radio wave. Wavelengths between radio waves and infrared are called TeraHertz radiation. Radio waves start at very long wavelengths LF or low frequency defined as 30kHz to 300kHz, MF or medium frequency from 300kHz to 3MHz, HF or high frequency from 3MHz to 30MHz, VHF or very high frequency from 30MHz to 300MHz, UHF or ultra high frequency from 300MHz to 3GHz and SHF from 3GHz to 30GHz. After that they are normally just called microwaves. Many microwave ovens operate near 2.4GHz which is only UHF.
If you're talking about how long it takes light to get from here to there ... all wavelengths of light, as well as all wavelengths of every other example of electromagnetic radiation, all travel at the same speed.
X-rays have the highest frequency in the electromagnetic spectrum.

The wavelengths of electromagnetic radiation extend from any long wavelength, withno upper limit no matter how long, continuously through all possible wavelengths, withno gaps, down to any short wavelength, with no lower limit no matter how short.
The longest wavelengths on the electromagnetic spectrum are called radio waves. They have the lowest frequencies and carry information through long distances.
Some types of electromagnetic radiation with longer wavelengths than visible light include infrared radiation, microwaves, radio waves, and long-wavelength radio waves. These forms of radiation have wavelengths that are not visible to the human eye but are used in various applications such as remote sensing, communication, and cooking.
The electromagnetic spectrum encompasses a wide range of wavelengths, from very long radio waves with wavelengths of kilometers to very short gamma rays with wavelengths less than the size of an atomic nucleus. The specific wavelength of electromagnetic radiation depends on the specific type of wave being considered.
Electromagnetic radiation, such as radio waves, microwaves, and infrared waves, fills space as long wavelength radiation. These forms of radiation have lower frequencies and longer wavelengths compared to visible light.
Electromagnetic radiation has the lowest energy due to its long wavelength and low frequency. In the electromagnetic spectrum, radiation with longer wavelengths, such as radio waves, carries lower energy compared to higher-frequency radiation like gamma rays.
This type of radiation would be classified as radio waves. Radio waves have long wavelengths and low frequencies, making them suitable for communication and broadcasting purposes.
We can only see visible light because our eyes are sensitive to the wavelengths of light within the visible spectrum. Other forms of electromagnetic radiation, such as infrared and ultraviolet light, have wavelengths that are either too long or too short for our eyes to detect.
The sun gives off a range of wavelengths, including both short and long wavelengths. The majority of the sun's energy is in the form of visible light, which falls in the mid-range of the electromagnetic spectrum. However, the sun also emits shorter wavelength ultraviolet radiation and longer wavelength infrared radiation.
Wavelengths in the radio wave region of the electromagnetic spectrum have the lowest energy. These waves have long wavelengths and low frequencies, making them less energetic compared to other types of electromagnetic radiation like gamma rays or X-rays.
The electromagnetic spectrum consists of various types of electromagnetic radiation, each characterized by a different wavelength. It includes gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves. These wavelengths range from very short (gamma rays) to very long (radio waves).
