Radiowave generator consists of a capacitor and an inductor. The area of the capacitor plates 0.025 m ^ 3, the distance between the plates is 1 mm, the dielectric constant of the dielectric e = 4. Determine the wavelength emitted by the generator, if it is known that a change in current of 2 A for 0.5 seconds in the coil induced emf is equal to 1 mV.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
