[tex]\boxed{\text{Radio Waves}}[/tex] have the longest wavelengths.
Further Explanation:
Electromagnetic waves are the types of waves that are produced due to interactions between electric and magnetic fields. These waves can be considered as a result of vibrations between oscillating electric and magnetic fields. All electromagnetic waves travel with speed of light but differ in terms of their frequencies and wavelengths.
Wavelength is the distance between two successive troughs or crests. The point of maximum displacement is known as crest while that of minimum displacement is called trough. It is denoted by and its SI unit is same as that of length and is expressed in meter (m).
The number of times any event takes place in unit time is expressed in terms of frequency. It is usually applied to waves including light, sound and radio waves. It is represented by [tex]\nu[/tex] and its SI unit is Hertz (Hz).
Electromagnetic spectrum is the arrangement of various electromagnetic radiations in terms of their respective frequencies or wavelengths. Electromagnetic spectrum in increasing wavelengths is written below.
Gamma Rays < X-Rays < Ultra violet rays < Visible rays < Infrared rays < Microwaves < Radio waves.
Therefore radio waves have the longest wavelengths.
