There is no longest wavelength. In the electromagnetic spectrum extremely low frequency waves can have wavelengths of less than 100 megametres (100,000 kilometres or 10^8 metres). Gravitational waves are likely to have much longer wavelengths.
Generically speaking, radio waves have the longest wavelength and gamma rays have the highest energy.
the lowest frequency Lester was here
wavelength = velocity/ frequency wavelength = 330/256 wavelength = 1.29 (to 3 sig fig) 1.30
Gamma rays have the shortest wavelength. Electromagnetic wave is a kind of energy being propagated even through free space (vacuum). It is classified based on the mode of producing it as Radio waves, micro waves, infra red, visible, ultra violet, X-ray and Gamma ray. Out of these seven, radio waves have the lowest frequency and Gamma ray has the highest frequency. As frequency and wavelength are inversely related, radio wave would have the longest wavelength.
Wavelength and frequency are inversely proportional.
There is no longest wavelength for photons. It can be arbitrarily long.
"radio waves" have longest wavelength..
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Red light has the longest wavelength.
Red is the longest wavelength of visible light
Red is the longest wavelength of visible light
-- longest wavelength -- lowest frequency
The electromagnetic waves with the longest wavelength are called radio waves.
The color red has the longest wavelength of all the colors in the light spectrum.
The color red has the longest wavelength of any color.
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
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.
