Is it shown or shone?

Both shown and shone are past participles of verbs, but they are not synonyms. They are sometimes confused because of their similar spelling and sound.

Shown is the past participle of the verb show, meaning “demonstrate or illustrate something.” Shone is the past participle (and sometimes simple past) of the verb shine, meaning “emit light.”
