The given question is asking about wavelength.
Then certainly the given options must be some waves since every wave has a wavelength.
All the waves in the given options are electromagnetic waves.
The electromagnetic waves are formed from electric and magnetic fields
. The electric field and the magnetic field oscillate in different planes perpendicular to each other.
The electromagnetic waves exist for a wide range of wavelengths and these are understood by the electromagnetic spectrum.
Electromagnetic spectrum is like a chart that arranges the electromagnetic waves in the order of their wavelengths.
According to the electromagnetic spectrum, the order of the electromagnetic waves with respect to their wavelength is as follows:
Gamma rays < X-rays < Ultraviolet < visible light < infrared < radio waves
Final answer:-
Hence, gamma rays have the minimum wavelength and the infrared radiations have the maximum wavelength.
