Ondas - Período e frequência

I'm a Physics and Math teacher, and I post several quality video lessons on my channel every week, aiming to help each of you learn more easily. Help the channel grow by subscribing and leaving your comments on the videos you watch so that through your feedback, I can continually improve the lessons.   / auladobruz     / tiagobruz   https://t.me/auladobruz    / tiagobruz
