In 45:20 what is calculated is the BACK focal length. The focal length, more specifically, the effective focal length is measured from the second principal point. Therefore, we should know where is this.

how can i calculate the nodes in a standig wave ?

[@jacobvandijk6525]

Length of the cavity: L = n . (1/2 . wavelength), with n being the number of nodes
