What are examples of public goods?

Fireworks display and light house are good examples.

Public goods involves the types of goods with two properties 1. non Excludable( there are no boundaries as to who should use the good) 2. Non Rivalry(the quality of the good is not diminished if shared)

Examples includes: Firework display(non excludable as everyone can watch the beautiful display and they are non rival as, irregardless of how many people are watching there is not going to be any change in the quality of the firework display)
