Question

Fluorescent Tube data:

 

You should see a bright green emission line at approximately 546 nm.  Record the position of the green line that you see in the first row of the second column in the following table.  Do the same for the 436 and 405 nm wavelengths and write down the color that you think they look like in the third column. If you cannot see the 405 nm line write “not detectable”.
