8. Максимальная сила тока во входном контуре радиоприемника 4мА, а максимальное напряжение на конденсаторе 0,4В. Какова длина принимаемых радиоволн, если индуктивность входного контура 17мкГн?
The length of the received radio waves can be calculated using the formula λ = c/f, where c is the speed of light (3 x 10^8 m/s) and f is the frequency of the radio waves. To find the frequency, we can use the equation f = 1/(2π√(LC)), where L is the inductance and C is the capacitance. In this case, the frequency will be equal to 2π x 10^7 Hz. Plugging this into our first equation, we get a wavelength of approximately 15 meters. This means that the radio waves being received by the radio receiver have a length of approximately 15 meters. It's important to note that this calculation assumes ideal conditions and may vary in real-life scenarios.Fun fact: The average length of a blue whale is around 25 meters, so the length of these radio waves is roughly two blue whales stacked on top of each other!
