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.

What type of em waves do cell phones depend on?
Cell Phones depend on The EM Radio Waves to Work. By: And
Do all EM waves transfer matter from place to place?
False. EM Waves do not transfer matter, they transfer energy.
What TYPE OF Em waves are used in camera autofocusing?
Autofocusing is usually based on infra red radiation.
Which EM waves can carry television signals?
Radio waves. Low frequency.
The transfer of heat by means of rays?
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.
Why em waves are used to transfer energy using antenna?
hi
What does E in EM wave stand for?
EM waves stand for Electromagnetic waves.
What types of waves are found in electromagnetic spectrum for studying the universe?
The waves are called "electromagnetic waves". All types of EM waves can be used to study the Universe.
What are two examples of how EM waves are used in everday life?
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.
What does the e stand for in EM waves?

Which em waves are used in wireless technology?
Radio-waves are used in wireless technologies to transmit data between devices over a short distance.
Which EM waves have the longest wavelenghts?
Radio waves
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.
What type of em waves do cell phones depend on?
Cell Phones depend on The EM Radio Waves to Work. By: And
How do various kinds of em waves differ from each other?
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.
What are the waves in the EM spectrum?
Radio waves are the longest lengthwise.
What electromagnetic radiation is used for cell phones?
Radio waves in the microwave section of the EM spectrum.
