Hint: The part of the electromagnetic spectrum having a frequency greater than the visible spectrum is dangerous for the human body. So, frequency less than the visible spectrum is used for daily applications.
Complete step by step answer:
a). For radar systems used in aircraft, navigation uses the microwave or radio wave part of the electromagnetic spectrum. Because of longer wavelengths. The microwaves are produced by the ballistic motion of electrons under the electromagnetic field in a vacuum tube. The radio waves are produced by the accelerated motion of electron or charged particles.
(b). For the treatment of muscle strain, the infrared part of the electromagnetic spectrum is used. The infrared waves are produced by hot bodies.
(c). For the diagnostic tool in medicine, the X-rays are used. The x-rays are produced by the high energy electrons bombarded on the metal of high atomic number.
Note: Try to remember the application of different parts of the electromagnetic spectrum.
Other than above mentioned spectrum the visible part helps us to see the wonderful colors of nature, the UV rays are used in industrial processes, rays are used in sterilization and disinfection, etc.
