Which characteristic is common to microwave radar, waves ,and television waves? a they are different types of waves with frequencies higher than radio waves b they are all radio waves with frequencies lower than visible light c they are all radio waves with wavelength shorter than visible light

B they are all radio waves with frequencies lower than visible light

Explanation:

The electromagnetic spectrum classifies all the electromagnetic waves according to their frequency. In order from highest to lowest frequency, we have:

Gamma rays

X-rays

Ultraviolet

Visible light

Infrared

Microwaves

Radio waves

In particular, radio waves are the electromagnetic waves with lowest frequency (and longest wavelength), usually less than 300 GHz ().

Microwaves radar, radio waves and television waves are all examples of radio waves, which have frequencies lower than visible light. Radio waves are generally used for long-range communications, because given their long wavelength they are able to "bypass" huge obstacles like mountains or building, without being absorbed.
