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.
EM waves cannot be used in SONAR because water is a conducting medium and thus EM waves would get shorted
micro waves light
EM waves stand for Electromagnetic waves.
EM waves or electromagnetic waves is radiant energy.
hi
EM waves stand for Electromagnetic waves.
EM waves are both Transverse and Longitudinal.
The waves are called "electromagnetic waves". All types of EM waves can be used to study the Universe.
Radio-waves are used in wireless technologies to transmit data between devices over a short distance.

Electromagnetic waves have no odor.
