… and is often used in radio circuits to create a third completely different frequency, sometimes referred to as a … When the wave reaches the bottom (grounded end), the wave has traveled twice the length of the coil (1/4+1/4-1/2 2), which means it is 180 degrees out of phase from when it started. If the coil is tuned properly, …
