What is the electromagnetic wave which has longest wave length?

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.


What are electromagnetic waves with the longest wave lengths and the electromagnetic waves with the shortest wave lengths?

The longest wavelength corresponds to long wave radio, I think the longest used is about 2000 meters. The shortest are gamma rays, which occur in radioactivity, these are from about 10-11 meters down.

An electro magnetic wave known to possess the longest wavelength?

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.


Wavelengths in which position on the electromagnetic spectrum have the lowest energy?

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.
