The electromagnetic wave with the longest wavelength is ; ( C ) Infrared
The electromagnetic wave with the longest wavelength from the listed electromagnetic waves is the Infrared with a wavelength of around 10⁻5 m.
Difference between wavelengths
The longer the wavelength of an electromagnetic wave the shorter the frequency of the wave because the wavelength of an electromagnetic wave is calculated as ; λ = c/f
Where :
- c = velocity
- f = frequency
- λ = wavelength
Hence we can conclude that The electromagnetic wave with the longest wavelength is ; Infrared
