Extremely low frequency (ELF) waves have wavelength of the order of 100 megametres ( = 100,000 kilometres).
Radio waves
Radio waves are the longest lengthwise.
Radio waves have the longest wavelengths among all types of electromagnetic energy. They have wavelengths ranging from a few millimeters to kilometers.
whatb type of EM waves do you think that are most usefu?
Radio waves have the longest wavelength in the electromagnetic spectrum (EM), and are pure energy, they have no mass.
Cell Phones depend on The EM Radio Waves to Work. By: And
Radio Waves. Their wavelength is 103 meters (1 kilometer). Because of this, their waves have the lowest frequency.
We have several names for E&M waves, depending on their wavelength. "Radio" is one of the names ... typically the name we use for the longest class of waves.
Electromagnetic (EM) waves are arranged in the spectrum based on their wavelength or frequency. From longest to shortest wavelength/frequency, the EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. This arrangement is important because each region of the spectrum has unique properties and interactions with matter.
EM waves stand for Electromagnetic waves.
The types of waves in the electromagnetic spectrum include radio waves, microwaves, infrared radiation, visible light, ultraviolet light, X-rays, and gamma rays. These waves differ in their frequencies and wavelengths, with radio waves having the longest wavelength and lowest frequency, while gamma rays have the shortest wavelength and highest frequency.
The seven types of electromagnetic waves, in order of increasing frequency, are radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of wave has a unique wavelength and frequency, with radio waves having the longest wavelength and lowest frequency, while gamma rays have the shortest wavelength and highest frequency.
