What sound effect is it that plays in Naruto ep: 39 at approx 6:32?


This is a common sound effect used in anime to indicate sudden realization
often paired with widened eyes and a beam striking through his/her head. I
don't know what it's called. I checked on the internet as much as I could and
even looked through soundeffects fandom, but I couldn't find it because I
don't know what it's called! Halp.

Thanks
