Answer: All of the waves in the electromagnetic spectrum are transverse waves.
Explanation:
Electromagnetic spectrum is a continuum of electromagnetic waves. These waves are arranged according to wavelength and frequency.
Electromagnetic waves are transverse in nature. In the transverse wave, the particles of vibrations in the medium travels perpendicular to the direction of propagation of the wave.
They travel with the speed of the light in the form of sinusoidal wave.
Therefore, all of the waves in the electromagnetic spectrum are transverse waves
