Electromagnetic waves
The part of the electromagnetic spectrum with the lowest frequency and longest wavelength is radio waves. They are used for communication, broadcasting, and radar.
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
-- longest wavelength -- lowest frequency
No. In the visible portion of the electromagnetic spectrum, the waves at the red end have the longest wavelength (lowest frequency), and those at the violet end have the shortest wavelength (highest frequency).
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
The three colors with the longest wavelength are red, orange, and yellow. They have the lowest frequency and highest energy among the visible spectrum of colors.
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
The longest wavelength in the visible light spectrum is at the red end (at about 750nm) the lowest is violet (450nm). For a given intensity source the energy that can be generated is equal.The answer you are looking for is 720-680nm
As you move from gamma rays to radio waves on the electromagnetic spectrum, the wavelength gets longer and the frequency decreases. Gamma rays have the shortest wavelength and highest frequency, while radio waves have the longest wavelength and lowest frequency.
Extremely low frequency (ELF) radio waves. They can have wavelengths of over 60,000 miles (100,000 km) and frequencies from 3 to 300 Hz.
Radio waves have the lowest frequency and longest wavelength there arent any sub-catagories it just goes (lowest to highest in frequency) Radio wave, microwave, infrared, Visible light, ultra violet light, x-ray, then gamma ray with the shortest wavelength and highest frequecy
