What type of waves are used in wireless technologies?

Mechanical Waves
Electromagnetic Waves
Sound waves
Surface Waves

The correct answer is: Electromagnetic Waves

Wireless technologies such as radio, television, and cell phones utilize electromagnetic waves for transmission. These waves can travel through a vacuum and do not require a medium to travel through, making them ideal for wireless communication. Mechanical waves, like sound waves, require a medium to travel through and therefore are not suitable for wireless technology. Surface waves are also not used in wireless technologies as they are confined to the surface of a medium and cannot travel through a vacuum. Therefore, B is the correct answer.
