Visible spectrum ore crusher priceThe focus of Lesson 2 will be upon the visible light region the very narrow band of wavelengths located to the right of the infrared region and to the left of the ultraviolet region Though electromagnetic waves exist in a vast range of wavelengths our eyes are sensitive to only a very narrow band -light region visible-,is 400 nm in the UV region or visible light region Best Answer Please reread the question It states that a transition from 2->1 emits a 400nm photon It then asks what is emitted by a 3->1 transition This will not be a 400nm photon but something more energetic Something a bit more energetic than 400nm is UV …… Get More
