Classify the waves as being mechanical or electromagnetic. microwave ocean wave seismic wave radio wave

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.
