Sequence of electronic impulses or radio waves transmitted or received
Regular repeating actions such as sound waves, light waves, or radio waves have a certain frequency, or number of waves per second.
To be guided to a target automatically, as by means of radio waves.
Just as a radio antenna will resonate with and absorb certain radio waves, nanostructured optical antennas can resonate with and absorb visible and infrared light.
The progressive blocking of light, radio waves, or other radiation from a celestial source during such a passage.
Every night, the radio waves passed through the walls, and the waves came upon her like waves, rushing her to the dawn, which had not closed her eyes all night.
And they use lasers, radio waves, or even dense metal tubes, known as "Rods from God", dropped from space to do the damage.
After switching off of the device, the crystal starts re-emit the recorded information in the form of ultra low amplitude radio waves.
As we'll see, there's also a matter of paying for the right to use radio waves, a privilege that is only granted after payouts in the billions of dollars.
We directed radio waves around the globe.
The difference is that radar depends on radio waves.
Cellphones send signals to nearby towers via radio frequency waves, a form of energy similar to FM radio waves and microwaves.
Television is the transmission and reception of images of moving objects by radio waves.
The radio waves which pass through the brain are not necessarily registered by one who has a brain transmitter.
As a result, a single radio wave from an FM station is only a few meters long, about the size of a car. An AM station is putting out radio waves that are hundreds of times as long!
Instead of going through the power lines, some systems use radio waves to communicate, which is also how WiFi and cell phone signals operate.
Not that the earth blocks all that but the earth blocks the low-frequency stuff for sure, including radio waves and that can be brought into you just by being barefoot.
transmit(a signal,etc)by radio waves
"Antenna: Component of radio, television, and radar systems that directs incoming and outgoing radio waves."
Permeable to electromagnetic radiation of specified frequencies, as to visible light or radio waves.
My point here is not to say, oh, you idiot, Plato, why didn't you think of radio waves?
At present, the electronics that transmit and receive the radio waves used in wireless devices are too large to be used within individual chips.
As matter accretes toward the black hole's center, tidal forces and other phenomena ejects superheated material into space, which makes the black hole a major source of radio waves.
The light emitted by the sun is called light waves, the waves transmitted by radio stations are called radio waves, and sound is carried by sound waves.
radio telescope( apparatus for finding stars,tracking spacecraft,etc by means of radio waves from outer space)
Near some sprites, the team also found radio waves in 310-mile-wide (500-kilometer-wide) bands-and these radio waves were most likely being emitted by high-speed particle beams.
Ten years later Spencer patents a "radar range" that cooks with high-frequency radio waves; that same year, the Tappan Stove Co. introduces the first home microwave model.
Will's body was failing, but his mind existed in the form of radio waves, and we could upload his consciousness, and we could save him. 威爾的身體逐漸衰竭，但他的意識以電波的形式存在，我們可以上載他的意識，我們可以救他。
You turn on your radio, the radio waves passing by, boom, properly tuned, you detected it.
By now an idea obsessed him: that directed radio waves could be used to heat and destroy cancer cells.
Pedersen had made them himself, with the help of an enormous array of antennas that can hurl several megawatts of radio waves into the upper atmosphere, creating brilliant light shows in the sky.
Ice, which is transparent to radio waves, also sends back left-polarized waves.
The radiant energy used in such measurements may vary from X rays, through visible light, to radio waves.
transmit messages via radio waves.
A cellphone is a miniaturized radio receiver and transmitter, and the health concerns focus on the radio waves it gives off.
a housing for a radar antenna; transparent to radio waves.
Because radio waves are millions of times longer than visible light, a collecting dish of a 10-meter radio telescope might only resolve an area of sky the size of the moon.
Evaporation ducts, or tropospheric ducts in general, can guide radio waves to distances far beyond the horizon with less attenuation, and then severely impair some certain radio wave system.
I tried to imagine how the vibration of my voice, carried by radio waves at 186000 miles a second were covering the 10000 miles - but I simply could not.
a telephone that communicates by radio waves rather than along cables.
The year is 1887, and Heinrich Hertz is generating radio waves.
