Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
An electromagnetic wave of a frequency between about 10⁴ and 10¹¹ or 10¹² Hz, as used for long-distance communication.
- ‘What's the longest radio wave that therefore, has the lowest frequency?’
- ‘Working on the 13.56 MHz frequency, a radio wave ricochets off the chip, picking up a code that identifies the bearer.’
- ‘By building more complicated antennas, engineers can control the direction in which the radio wave is sent.’
- ‘These are transmitters that use radio waves to communicate with mobile phone handsets.’
- ‘When a radio wave crosses the boundary of different layers of ‘material,’ an echo is generated that produces a sort of ‘fingerprint’ of the specific materials.’
- ‘One of the most ubiquitous and useful technological tools of the 1950s was the radio wave.’
- ‘All in all, what's left is a distinctive set of pulses, the imprint of the radio wave being intermittently altered by the gravity wave.’
- ‘The problem is that the Government gives such a small band to operate in and effectively the radio wave we use for the key fob is restricted because of that.’
- ‘Once out of its protective box, any kind of radio wave can potentially ignite it until it is inserted inside the bomb.’
- ‘A vision signal is relayed to the electronic screen via a variety of methods - usually cable or radio wave, and the screen interprets this vision signal and then retransmits it via light.’
- ‘Heinrich Hertz carried out the first experiments with radio waves - the unit of frequency is named after him.’
- ‘MRI uses a magnetic field and radio waves to make a picture of your brain.’
- ‘When any part of the radio wave is reflected to the fuze from the target, an interaction or doppler signal occurs between the reflected transmitted wave.’
- ‘We know that radio waves and waves of all kinds of frequencies are constantly going through our bodies.’
- ‘The technology ‘sees’ the shapes made when radio waves emitted by mobile phone masts meet an obstruction.’
- ‘The local system will be delivered by radio wave directly to the user and will provide 24 hour connection.’
- ‘Light according to Maxwell is an electromagnetic wave, no different in essence to radio waves or the microwaves that heat up our ready meals.’
- ‘Terahertz radiation represents the last unexplored frontier of the radio wave and light spectrum, Nori said.’
- ‘It can also be modulated, like a radio wave, to carry information.’
- ‘The silence drew out, raining down on her ears endlessly until it grew its own sound, a buzzing like a radio wave.’
