The Figure Below Shows Three Distinct Types of Pulsating Stars

Question 95

Essay

The figure below shows three distinct types of pulsating stars: Type I (Classical) Cepheids, type II Cepheids and RR Lyrae.Assume that you find a variable star whose period of pulsation is several days.You accurately measure its apparent brightness, but you misidentify its type, labeling it "Classical" instead of Type II, which would in fact be its correct type.What would be the effect in the determination of distance?
