When a police officer uses radar for speed control, the officer is using what kind of electromagnetic waves? A) radio waves B) gamma rays C) ultraviolet rays D) X-rays

It is the radiowaves, which are used by the radar system.  

•Transmission of radiowaves is done by the radar systems.  

•The majority of the objects reflect radio waves that can be determined by the radar system.  

•The frequency of the radio waves relies upon the application of the radar system.  

•The radar systems are usually determined by the frequency or wavelength band in which they operate.  

•The police radar systems transmit radio waves on a particular frequency, and in North America, the three frequency bands presently in use are K band, S band, and Ka band.  

Thus, the correct answer is option A, that is, radio waves.

Explanation:

A police officer using radar for speed control is using radio waves.

Radio waves is one of the forms of electromagnetic radiations that are known.

on the planet jupiter, the acceleration due to gravity is approximately 26 m s2 , roughly 2.7 times the acceleration due
