Why does your radio only work in park or neutral?
The radio waves don't follow the car when it is moving fast.
What properties make radio waves good for communicating?
The really nice thing about radio waves is that they will make the electrons in a piece of copper wire move; this means that they generate electric currents in the wire. In fact it works both ways: alternating currents in a copper wire generate electromagnetic waves, and electromagnetic waves generate alternating currents. The electric currents at "radio frequencies" (rf) are used by radio and television transmitters and receivers. I use frequencies of 145MHz (VHF), 14MHz (20m HF) and 3.7MHz (80m HF).
Why did it take 7 minutes for the radio signal to travel from the Curiosity back to earth?
Radio waves travel "at the speed of light" which, though very fast, is still a finite speed. Mars is far away so it takes 7 minutes for the radio waves to travel the distance from Curiosity to the Mars orbiter that then relays radio communications to Earth. How much delay in the electronics of the relay station in the orbiter and the electronics on Earth I cannot be certain, but certainly a measurable amount though probably less than a few seconds.
What are the waves in the electomagnetic spectrum?
The speed of every electromagnetic wave is the same. That includes television waves, FM radio waves, heat waves, infrared light, green light, purple light and ultraviolet light waves, microwaves, x-rays, AM radio waves, bluetooth signals, taxi radio waves, garage- door-opener waves, and gamma ray waves ... because all of these waves are the same thing. Their speed is 299,792,458 meters per second, or 186,282 miles per second.
Advantages in radio waves?
they have the maximum frequency..and they travel round the earth in just one secondBy:KellyTHE BENEFITS OF RADIO WAVESWhatever the wavelength is will depend on the type of transmitter you will use. Stars, sparks and lighting also give off different types of transmitter. When you hear your radio station get fuzzy it is being interfered by these transmitters.An "Atlantic 252" has about a 1 to 2 km in wavelength. People call this a long wave compared to others.　The radio, like AM stations are used for radio stations. The wave is about 100m in wavelength. This is about a medium waveRadio waves have enabled better navigation of aircrafts and ships. For instance in the radar form, it is used for sending signals and then receiving them from their reflections. Radio waves sent from GPS satellites can be used by receivers for an exact indication of location. GPS systems are installed in most vehicles to provide the users with a map at all times. This technology was arrived at because of radio waves.　　　　　　DANGERSIf you have a large amount of radio waves people say it can cause disorders like cancer, leukemia. They say that if you have power cabled above, or near your home it can affect your health.　　　　WEBSITE SOURCE"The Electromagnetic Spectrum: Radio Waves." Andy Darvill's Science Site: Home.

How fast do radio waves travel in a empty space?
6 billion km.
How fast is electronic dynamic waves travel to the space.?
I assume you mean electromagnetic waves. In outer space, they will travel at the speed of light (since light is also an electrodynamic wave). This speed is about 300,000 kilometers per second.
How fast can a radio wave travel to space and back to earth?
Radio waves travel at the speed of light which, in a vacuum, is about 3 x 108 meters per second.
Why does your radio only work in park or neutral?
The radio waves don't follow the car when it is moving fast.
What are three things radio waves can do?
Here are a few things that radio waves can do: 1. Communications (TV, Commercial radio, Ham radio etc.) 2. Heat things up, (Microwaves are just extremely short radio waves) 3. They can travel extremely fast (At the speed of light)
How fast do waves of radiation travel through space?
About 30km/hour
How fast are Love waves in kilometers per second?
350 K k/s
How fast do sound waves travel in kilometers per hour?
Sound travels at 1,225.044 kilometers per hour at sea level.
How fast do you travel through space?
500 Kilometers per hour
How fast does a space shutle return to earth?
27,875 kilometers a hour
How fast does theRadio waves travel?
Radio waves travel at the speed of light 300 Million meters/second, 300e6 meters/second
How fast does a shuttle need to travel to get into space?
11 kilometers per second.
