Quizplus · Accepted Answer

The frequency of the radiation emitted by a Josephson junction when a voltage is applied across it can be calculated using the Josephson frequency-voltage relation: $f = \frac{2eV}{h}$, where $f$ is the frequency, $V$ is the voltage, $e$ is the elementary charge ($1.602 \times 10^{-19} C$), and $h$ is Planck's constant ($6.626 \times 10^{-34} Js$). For a voltage of 3 µV ($3 \times 10^{-6} V$), the frequency is approximately 1450 MHz.
