Respuesta :
Answer : The correct options are, radio-waves, microwaves, gamma-rays, X-rays, visible rays.
Explanation :
Electromagnetic spectrum : It consists all the electromagnetic radiation with different wavelengths.
Electromagnetic waves : It is a wave in which the two vectors (electric field and magnetic field) are vibrating mutually perpendicular to each other and in direction of the wave.
The gamma-rays, x-rays, ultraviolet-rays, infrared-rays, microwaves and radio-waves are the electromagnetic waves and are the part of the spectrum.
Hence, the correct options are, radio-waves, microwaves, gamma-rays, X-rays, visible rays.
