Answer :
Answer:
Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Radio wave among the type of all electromagnetic waves has the largest wavelength but the lowest frequency.
What is Wavelength?
It can be explained in terms of the separation between any two similar successive points on a wave, such as how the wavelength can be determined by calculating the separation between any two successive crests.
It is the total length of the wave for which it completes one cycle.
The wavelength is inversely proportional to the frequency of the wave as from the following relation.
C = νλ
where v is the wave's frequency and c is the speed of light λ
represents the wave's wavelength.
wavelength and the frequency of the waves are inversely proportional as the speed of the light is constant.
Radio waves have the lowest frequency among all the electromagnetic waves this means they have the longest wavelength as per the above relation between frequency and the wavelength of the electromagnetic waves.
Thus, we can conclude radio wave among the type of all the electromagnetic waves has the largest wavelength.
