| A radioactive source will emit these radiations at various frequencies, depending on its activity and its decay mode. |
| As gene frequencies change, natural selection acts on the outcome, the expression of those genes. |
| In the billions of years since, they have cooled to less than three degrees Kelvin above absolute zero, equivalent to microwave frequencies. |
| To transmit energy or a signal, the waves must come in a range of frequencies, which combine to form packets. |
| We know that radio waves and waves of all kinds of frequencies are constantly going through our bodies. |
| An atom will have many frequencies, some at radio wavelength, some in the visible spectrum, and some in between the two. |
