Physics : Voice 9

Hello, everyone who likes physics 🔭🩼📡 I am so sorry………..because these days I talked to much about something without science, therefore I want to add another episode. Thank you all the people, because you all ever give me the happy, interesting things, support, encouragement……..towards love. (I often do this to appreciate so many people, since I was so little, that’s why “姍姍” is such a famous name when I lived in Tamshui………….please don’t blam me about this behavior.) Today I quickly solve a wave’s reflection. And tell you a question that some people would wonder so loooooooooong. (😊 smile) My estimate…….: Taiwan tidy up so much things quickly already. Celebrate this! The whole new Taiwan has ready………(I think is rest first ready 😒)
