The correct answer is: B. Radio<\/strong><\/p>\n Radio waves are a type of electromagnetic radiation with wavelengths in the range of about 1 millimeter to 100 meters. They are used to carry information in the form of radio waves. Radio waves are used in a variety of applications, including radio broadcasting, television broadcasting, mobile telephony, two-way radio, satellite communication, radar, and navigation systems.<\/p>\n Mechanical waves are waves that propagate through a material medium (solid, liquid, or gas) by the repeated deformation of the medium. Sound waves are a type of mechanical wave. Sound waves are produced by vibrating objects. The vibrations cause the air molecules to vibrate, and these vibrations travel through the air in the form of sound waves.<\/p>\n Sound waves are not used in wireless networks. Wireless networks use radio waves to transmit signals. Radio waves are electromagnetic waves, which are waves that can travel through the air without a material medium.<\/p>\n Magnetic waves are not used in wireless networks. Wireless networks use radio waves to transmit signals. Radio waves are electromagnetic waves, which are waves that can travel through the air without a material medium. Magnetic waves are waves that can only travel through a material medium.<\/p>\n None of these is not the correct answer.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Mechanical” option2=”Radio” option3=”Sound” option4=”Magnetic E.
