[1] proposed that the new approach to photon momentum, introduced by Umul [2], was not correct, because they obtained a negative energy expression for the absorbed photon. In this comment, we show that this proposal is wrong, since the related authors made a mistake in their derivations.eninfo:eu-repo/semantics/openAccessEditorial14834234310.1016/j.ijleo.2017.09.034
