Radio frequency (RF) is a rate of oscillation in the range of around to , which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

Significant progress has been achieved in many countries in terms of increased school attendance by indigenous children.

Normal financing is not forthcoming. Only grants from the US will reduce output volatility.

I will not blame him for the accident.

This event benefits no one.

French reconnaissance aircraft flew over the scene the next morning without reporting the incident to Turkish authorities.

LC circuits are used either for generating signals at a particular frequency, or picking out a signal at a particular frequency from a more complex signal.

Acoustic resonance is the tendency of an acoustic system to amplify a frequency that matches one of its own natural frequencies of vibration (its resonance frequencies ).

The accident happened because he wasn't careful.

No one was harmed in the incident.

This incident is called the Sinmiyangyo in Korea.

The original black and white standard, with its 15750 Hz line frequency and 4.5 MHz audio subcarrier, does not meet these requirements, so designers had either to raise the audio subcarrier frequency or lower the line frequency.

The Committee regrets that, in the absence of reliable data, it could not assess the nature and extent of the reportedly high incidence of domestic violence in the State party and the degree of enforcement of existing legislation for the protection of victims of domestic violence.

Similar dithering is apparent at the geopolitical level as well.
