| Now it is possible to coherently link the radio frequency and optical domains with a supercontinuum comb of frequencies. |
| As gene frequencies change, natural selection acts on the outcome, the expression of those genes. |
| An atom will have many frequencies, some at radio wavelength, some in the visible spectrum, and some in between the two. |
| Because white noise contains most sound frequencies, it is commonly used to mask other sounds. |
| We know that radio waves and waves of all kinds of frequencies are constantly going through our bodies. |
| Each group had its own radio frequency and had no knowledge of the frequencies used by the others. |
