Hello, @ángela-rojas,
Not very difficult with a regular expression, indeed !
Assuming that :
The word Wavelength, with that exact case, begins a line and is followed by, at least, one space character
The different numbers, beginning the following lines, are followed by a single space character
Just follow the few steps, below :
Move back to the very beginning of your file ( Ctrl + Origin )
Open the Replace dialog ( Ctrl + H )
Type (?-i)^Wavelength +|\R\d+ , in the Find what: box
Leave the Replace with: box EMPTY
Click on the Replace All button
Et voilà !
Notes :
The regex search looks, either, for :
The string Wavelength, with that exact case, followed by, at least, one space character ( + )
Some End of Line characters (\R ), immediately followed by, at least, one digit ( \d+ )
Whatever the case found, the overall match is deleted, due to the empty replacement regex
Best Regards

P.S. :
In case the
numbers, beginning the line, are followed by
several space characters, prefer the regex S/R, below :
SEARCH (?-i)^Wavelength +|\R(\d+) +
REPLACE ?1\x20
If the search must
not be
sensitive to
case, just change the
(?-i) part by the
(?i) syntax
