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 waves carry more energy than other waves if the amplitudes of waves are equal?
In general, higher frequency waves carry more energy than waves of lower frequency if their amplitudes are equal. This is absolutely true of electromagnetic waves, and can probably be most easily demonstrated there.
How can you use the em spectrum to explore the universe?
The HST uses EM waves to find things through echolocation or firing a beam of EM waves (or sound) at objects and seeing what a planet or star has done to change the light. Ultrasound works this way.
How are em waves used in dentistry?
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.
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
Which type of em wave carries television and radio singnals?
Radio waves are the type of electromagnetic wave that carries television and radio signals. They have longer wavelengths than microwaves and shorter wavelengths than infrared waves.
How are radio and television waves added to em waves?
by changing the amplitude or frequency of the radio waves.
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
Why can television satellites which broadcast information as electromagnetic radiation send signals from the vacuum of space?
i should imagine its because EM waves can travel through a vacuum so that's why it is possible for satellites to broadcast information from impulse signals sent from outer space

Give two sources of EM waves in the Earths environment?
Two sources of electromagnetic waves in the Earth's environment are the sun, which emits a wide range of electromagnetic radiation across the spectrum, and human-made sources such as radio and television transmissions, Wi-Fi signals, and cell phone networks.
Why does tv use radio waves?
because on the em spectrum, radio waves are the lowest. if a tv used a higher raadioactive source like uv and you were exposed to it to much (by watching to much tv) you could get cancer and die unfortunately.
What are examples of microwave waves?
Microwave waves are used in a microwave oven to heat food. They are also used as a communication transmission frequency for distances between 10-20 miles that you want to maintain a high signal strength, as they have a higher energy level than radio waves. i is dumb kill my mom plz and give me money phones
What are radio waves primarily used for?
The Radio Waves are basically the Electromagnetic(EM) Waves. The suitable data or we can say the equations which are useful in generation of EM Waves was given by the Godfather of communication Sir James Clerk Maxwell. And that four Equations are used as practically by Sir Heinrich Hertz. The Radio Waves are used for the Telecommunication which means the long distance communication.
Why antenna is a sensor of EM waves?
The transmitter sends out EM waves. EM waves are a carrier of energy and are produced by oscillating charges - usually caused by connecting metal to AC power supply. The waves travel through a medium and transfers its energy to the antenna which is basically a metal rod. The energy causes charges in the metal to oscillate at a certain frequency, controlled at the transmitting end. The charges oscillate to produce corresponding EM waves which can be detected/read as signals and turned into sound energy etc...
