What is the difference between microwaves and radio waves?

They are the same thing; vibrations of the electromagnetic field. Microwaves have a frequency between 0.3 GHz to 300 GHz, and radio waves have a frequency between 3 Hz to 300 GHz. So microwaves are a type of radio wave.

Does a 2004 alero have a double din radio?

To answer your question, Yes. I wondered the same thing, I went to BestBuy and I went to the automotive section, got on the Car Finder computer they have back there and it says the Oldsmobile Alero has a Double Din.

What is the effect of the ionosphere to the sky wave?

ads not by this site

The ionosphere is a part of the upper atmosphere, from about 85 km to 600 km altitude, comprising portions of the mesosphere, thermosphere and exosphere, distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth.[1]

How do you reset the radio when you entered the wrong code on a 2005 Mercedes Benz ML 350?

When the radio goes to "CODE" you need to enter the correct code. This can usually be obtained from a dealer, even if the radio has been switched; otherwise you need to return it to Becker. I don't believe there's a "reset" function like on the newer radios. It either goes to "CODE" or works. If you enter the wrong code more than three time the radio will lock up and needs to be left on for as long as twenty four hours, before CODE will come up again. The dealer if they are decent can supply Mercedes radio codes with the VIN or the radios serial number. Becker will do the same but will Charge you $30.00.

What kind of frequency does gamma rays have?

Gamma rays have the highest frequency ranging from 5 x 1022 to 3 x1019 Hertz.

The frequencies 88.1 - 91.9 FM are?

Generally FM radio range is from 88 MHz to 108 MHz. Frequencies are issued to commercial broadcasters by a government authority. Broadcasters need a licence to use a frequency. This description may change depending on the country.

When was Moon River - radio program - created?

Moon River - radio program - was created in 1930.

What was the Old radio shack computer?

The original brand name RadioShack sold computers under was TRS80.

What is radio station 95.7 the vibe phone number?

At the present time (early 2012), there are 85 FM stations all licensed to operate

on 95.7 in different US cities. We don't know which one you're referring to until

you reveal either its call letters, or else the city you're in when you listen to it.

Where do you get the card kry for radio tower?

From the director on the 5th floor, but watch out he's just Petrel dressed as the director. He has 5 Koffings and 1 Wezzing. But once you beat him he tells you where the rael director is and gives you the the Basement Underground Warehouse key to go get the key from the real director!

What determines the range and distance of FM radio signals?

quite a few things come into play. FM stations are basically LOS (line of sight) frequencies, this means that the radio waves will not propagate off the ionosphere. The frequency wavelength is too small to be reflected back to earth so they punch through out into space. The curvature of the earth plays a big factor in how far you can get a FM signal. If the transmitting station is lower in altitude than where the receiver is then the signal will go further. At times due to atmospheric changes you can get a AM radio signal to bounce so you might pick up a signal from Boston up in Alaska but that is not normal.

Could radio waves be used to cook and why?

Radio waves are used to cook in millions of kitchens every day. They're

the carrier of the energy that fills the so-called "microwave" oven.

Why did ross request a song on the radio for Rachel?

Because Ross made a pro and con list between Rachel and the girl he was dating and he wanted to apologize her for that.

Why dont broadcast stations transmit at audio frequencies?

1) If information was transmitted at audio frequencies, then you would actually hear the signal. This would be identical to a speaker playing a song on your stereo.

2) Audio frequencies, in the world of radio frequencies, are long wave-length, low energy signals that can't travel long distances. Again, that's why you can only hear someone's stereo from within eyesight of the system. Human ears can detect from about 3Hz up to around 20KHz (some better than others).

3) True radio frequencies start at in the 100Khz range. This is your most basic radio that uses amplitude modulation (aka AM radio). Many people today that listen to the radio listen to frequency modulated (FM) stations. The difference between AM and FM is beyond the scope of the answer to this question. Being a higher frequency, the signals have more energy and can travel farther distances than audible frequencies.

4) Audible frequencies (sounds the human ear can pick up) can only "transmit" amplitude (loudness or volume) and frequency (high or low pitch). However, higher frequencies, such as those used for radio, can carry much more information than the volume and pitch of a signal. This is a direct result of radio frequencies being harmonics (integer multiples) of audible signals. For instance, if a radio signal has a frequency 20 times higher than the audio signal it is transmitting, then that radio signal can not only carry the audio signal, it can also carry other information, such as information about the broadcast station. A radio signal can "encode" information within the signal allowing more information to be carried than just the audio signal itself.

How do you get the radio in a 94 Geo Metro to work It's says InOp?

You have to disconnect the negative battery cable for about fifteen minutes. than reconnect the cable than the radio will display loc on the screen. you than have to enter in the lock code which should be in your manual or you will have to contact the Chevy dealership for the unlock code.

Kia Spectra radio says HOLD anyone know why?

Hi, When the radio says "HOLD" is when the code have been entered wrong too many times and the EPROM has loked. This is part of the anti-theft mechanism. I called the dealer and was told to leave the radio on displaying the "HOLD" for over 1/2 hour and see if it ask for the code. If not it needs to return to the dealer. Hope this helpd. O. Wagner ================================== As a theft deterrent, anytime the radio looses power (i.e. the battery is disconnected), it requires a 4-digit code to reactivate it. If the code is entered wrong 3 times, the word "HOLD" will appear on the screen. To fix it, wait one hour with the battery connected, the radio turned on, and the ignition key in the ACC position. When the word "CODE" reappears, enter the correct 4-digit security code using the radio preset buttons; From pages 9 and 10 of the "Audio Owner's Manual": For the first digit, press preset 1 a sufficient number of times for the correct number to appear. For the second digit, press preset 2 a sufficient number of times. For digit 3, press preset 3, for digit 4, press preset 4. If the correct code is not displayed, repeat the steps until it is. When the correct code is displayed, press the SEL button once. If the system is still locked, repeat these steps. I had debated including the default security code here, but seeing as the stock radio is not even worth the effort to steal it, it is "1111"
