PhET 互動式模擬教材

希望在波的干涉部分能夠加入，用輸入數字的方式調整波長、兩波源的相位、兩波源距離，及整體觀察水面不夠大。 希望你們能看到

裡面的實驗圖示、實驗中的各項參數設定，非常淺顯易懂，對於學習很有幫助，期待能更新更多實驗提供使用～～

請問如何將語言改為英語

If you arrived here from M.I.T. open courseware looking for the normal mode simulator don’t waste your time, it isn’t included.

Hello, I am a student and was first introduced to PhET lab on a web browser for science and just got the app and it is better then on the web browser, on the app it is very easy to find simulations you liked because you can favorite them and then just have only favorites show, the app is definitely worth the 99 cents.

I can’t offer enough applause and appreciation for what a valuable and wonderful resource this is. The variety and quality of the simulations continues to grow and has been invaluable in my teaching practice for many years. Keep up the good work!

This is a very good learning tool if your not sure you want it you now know its worth it! Get it! Its very good for learning.

Highly recommend for parents and teachers as tool to help kids explore math and science concepts. Great app!

I normally use PhET simulations within my Nearpod presentations but downloaded the app specifically for my son in third grade. I love that we can access the math sims offline so he can practice on his device anytime. And I found out the app will translate (at least to Spanish) if you change the device language setting! 😱♥️🌎

The best app for science and math education out there! Love that all the translations are now available on the app!
