Answer:
Micro waves and radio waves are electromagnetic waves while ocean wave and seismic wave are mechanical waves.
Explanation:
Electromagnetic waves do not require a medium for propagation. They can travel along vacuum just like they travel through matter.
Further examples of electromagnetic waves are x rays, infrared waves etc.
Spectrum of electromagnetic waves in the increasing order of frequency is radio waves, microwaves, infrared waves, visible light, ultraviolet, x ray, gamma ray.
Mechanical waves require a medium for propagation. Thus they cannot travel through a vacuum.
Sound wave is an example of mechanical wave.
Answer:
microwave and ocean wave are mechanical wave, seismic and radio wave are electromagnetic wave.
