Contact - website error #1
Description
Hi, as the last resort of contacting you, because I found no email nor other way on your website at all, I would like to report an error in https://www.experimental-engineering.co.uk/helium-neon-lasers/theory-modes-coherence/: you state "1 GHz at 632.8 nm: 1.335 nm." but it should be in "pm", instead.
Please consider leaving some easier access means of contact on your website.
Feel free to delete this message afterwadrs.
