| We see frequencies of hundreds of hertz, or hundreds of revolutions of the disk per second. |
| It was 1,660 hertz, in the range of frequencies expected to emanate from an exploding star. |
| And he actually employed a 27 hertz frequency through the first part of the film to induce unease. |
| The other instrument is sensitive to even lower frequencies, ranging from less than 0.1 to 400 hertz. |
| Different frequencies, measured in hertz, or cycles per second, indicate different levels and types of activities. |
| A gravity wave with a frequency of 1,000 hertz, for example, spans nearly 200 miles from peak to peak. |
