EM waves stands for Electromagnetic Waves. The EM waves used in dentistry are usually X-Rays. These electromagnetic waves go through your skin and other body tissue (don't worry it's not very harmful or bad for you). And reflect off your bones. Think of it as a camera, the X-Ray machine sends out a flash, then takes the picture. This 'picture' shows where your bones are and whats happening to them, like, are they coming out as an adult tooth? or will you need braces in a few years. That sort of thing.

False. EM Waves do not transfer matter, they transfer energy.
Autofocusing is usually based on infra red radiation.
Radio waves. Low frequency.
Radiation is the means of heat conduction through electromagnetic (EM) waves. These waves are known as Thermal radiation and differ from other EM waves as Radio waves, Microwaves etc. The other two methods of heat transfer are Conduction and Convection where both require a medium (such as air, water etc.) for the transfer to take place.
hi
EM waves stand for Electromagnetic waves.
The waves are called "electromagnetic waves". All types of EM waves can be used to study the Universe.
EM waves are used in everyday life through technologies like cell phones, which use radio waves for communication. Another example is in microwave ovens, which use microwaves to heat food quickly and efficiently.
EM waves stand for Electromagnetic waves.
Radio-waves are used in wireless technologies to transmit data between devices over a short distance.
Radio waves
EM waves are both Transverse and Longitudinal.

There are two main types of EM waves. Magnetic waves and Electronic waves. They exist at orthogonal relationships with M waves and E waves at 90 degrees to each other.
Radio waves are the longest lengthwise.
