Lithium has a work function of 2.3ev. If 400nm light is incident on it, what is the maximum kinetic energy ? Chemistry Bohr Model of the Atom Calculations with wavelength and frequency
No. A comma precedes such as when what follows is an example of whatever went before. In this case, it is nonrestrictive. (For nonrestrictive constructions: use a comma.).
Perhaps I do this wrong in my own writing, but I do not underline punctuation (comma, period, exclamation point, question mark, colon, semicolon, etc) when the preceding word is underlined unless that punctuation mark is part of the title, as in Oklahoma! or Stomp!.
