Thank you! Temperate phages can undergo either lytic and lysogenic lifecycles or switch between the two based off of the phage and host cell genetics. As well as depending on the need of the phage, for reproduction (lytic cycle) or for more of a survival/growth need (lysogenic cycle).
Turbidity is a cloudy appearance in the plaques where phages have interacted with the host bacteria. Lysogenic phages do exhibit this type of plaque because the bacteria isn’t being killed/lysed and instead the phage DNA is incorporating with the host cell DNA.

Great presentation! Why do temperate undergo both lytic and lysogenic life cycles?

Why do you mean by turbidity? Why don’t lysogenic phages create this type of plaque?
