Great quiz, always love to see physics based quizzes. Would it be fair to accept gamma for photons? Especially considering the symbol.

Thanks for the comment. I am glad you enjoyed the quiz.

I appreciate your suggestion regarding 'gamma', but within physics, the 'γ' is used to describe photons as a whole and not merely gamma rays (the 1905 discovery of photons by Einstein should be sufficient to lead to 'photons', while gamma rays—discovered by Rutherford in 1900 and which, admittedly, also use the 'γ' symbol—are not a larger class of elementary subatomic particles).
