• The arrows represent the transition of electrons to different energy levels when heat is supplied

• The arrows of W represent emission in the UV region

• The smallest arrow of X represents a violet line in the emission spectrum

• The arrows of Y represent emission of electromagnetic waves with higher energy than those represented by X and W
