In the games, what item do you need to identify ghost Pokémon?
Answer Silph Scope
When visiting Lavender Town in the Generation I games, encounters in the Pokémon Tower will show generic "Ghost" Pokémon that try to scare the player away. Once players have acquired the Silph Scope, they can see which species a ghost Pokémon is, and they can battle and catch it.
